Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606274, here are decompositions:

  • 13 + 31606261 = 31606274
  • 223 + 31606051 = 31606274
  • 397 + 31605877 = 31606274
  • 463 + 31605811 = 31606274
  • 547 + 31605727 = 31606274
  • 577 + 31605697 = 31606274
  • 691 + 31605583 = 31606274
  • 757 + 31605517 = 31606274

Showing the first eight; more decompositions exist.
