Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479232, here are decompositions:

  • 101 + 31479131 = 31479232
  • 131 + 31479101 = 31479232
  • 149 + 31479083 = 31479232
  • 263 + 31478969 = 31479232
  • 401 + 31478831 = 31479232
  • 593 + 31478639 = 31479232
  • 761 + 31478471 = 31479232
  • 821 + 31478411 = 31479232

Showing the first eight; more decompositions exist.
