Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532138, here are decompositions:

  • 67 + 31532071 = 31532138
  • 229 + 31531909 = 31532138
  • 499 + 31531639 = 31532138
  • 739 + 31531399 = 31532138
  • 769 + 31531369 = 31532138
  • 877 + 31531261 = 31532138
  • 1021 + 31531117 = 31532138
  • 1039 + 31531099 = 31532138

Showing the first eight; more decompositions exist.
