Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625132, here are decompositions:

  • 73 + 31625059 = 31625132
  • 181 + 31624951 = 31625132
  • 193 + 31624939 = 31625132
  • 211 + 31624921 = 31625132
  • 271 + 31624861 = 31625132
  • 283 + 31624849 = 31625132
  • 349 + 31624783 = 31625132
  • 379 + 31624753 = 31625132

Showing the first eight; more decompositions exist.
