Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526148, here are decompositions:

  • 7 + 31526141 = 31526148
  • 61 + 31526087 = 31526148
  • 79 + 31526069 = 31526148
  • 97 + 31526051 = 31526148
  • 127 + 31526021 = 31526148
  • 167 + 31525981 = 31526148
  • 191 + 31525957 = 31526148
  • 197 + 31525951 = 31526148

Showing the first eight; more decompositions exist.
