Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489780, here are decompositions:

  • 67 + 2147489713 = 2147489780
  • 127 + 2147489653 = 2147489780
  • 193 + 2147489587 = 2147489780
  • 277 + 2147489503 = 2147489780
  • 307 + 2147489473 = 2147489780
  • 379 + 2147489401 = 2147489780
  • 433 + 2147489347 = 2147489780
  • 577 + 2147489203 = 2147489780

Showing the first eight; more decompositions exist.
