Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541612, here are decompositions:

  • 31 + 31541581 = 31541612
  • 43 + 31541569 = 31541612
  • 103 + 31541509 = 31541612
  • 163 + 31541449 = 31541612
  • 211 + 31541401 = 31541612
  • 331 + 31541281 = 31541612
  • 379 + 31541233 = 31541612
  • 433 + 31541179 = 31541612

Showing the first eight; more decompositions exist.
