Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625194, here are decompositions:

  • 47 + 31625147 = 31625194
  • 137 + 31625057 = 31625194
  • 431 + 31624763 = 31625194
  • 521 + 31624673 = 31625194
  • 563 + 31624631 = 31625194
  • 647 + 31624547 = 31625194
  • 683 + 31624511 = 31625194
  • 827 + 31624367 = 31625194

Showing the first eight; more decompositions exist.
