Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475132, here are decompositions:

  • 43 + 31475089 = 31475132
  • 61 + 31475071 = 31475132
  • 79 + 31475053 = 31475132
  • 103 + 31475029 = 31475132
  • 151 + 31474981 = 31475132
  • 163 + 31474969 = 31475132
  • 331 + 31474801 = 31475132
  • 349 + 31474783 = 31475132

Showing the first eight; more decompositions exist.
