Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495152, here are decompositions:

  • 5 + 31495147 = 31495152
  • 43 + 31495109 = 31495152
  • 89 + 31495063 = 31495152
  • 109 + 31495043 = 31495152
  • 149 + 31495003 = 31495152
  • 173 + 31494979 = 31495152
  • 229 + 31494923 = 31495152
  • 233 + 31494919 = 31495152

Showing the first eight; more decompositions exist.
