Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484742, here are decompositions:

  • 101 + 2147484641 = 2147484742
  • 131 + 2147484611 = 2147484742
  • 173 + 2147484569 = 2147484742
  • 251 + 2147484491 = 2147484742
  • 281 + 2147484461 = 2147484742
  • 503 + 2147484239 = 2147484742
  • 509 + 2147484233 = 2147484742
  • 521 + 2147484221 = 2147484742

Showing the first eight; more decompositions exist.
