Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25178, here are decompositions:

  • 7 + 25171 = 25178
  • 31 + 25147 = 25178
  • 61 + 25117 = 25178
  • 67 + 25111 = 25178
  • 199 + 24979 = 25178
  • 211 + 24967 = 25178
  • 271 + 24907 = 25178
  • 331 + 24847 = 25178

Showing the first eight; more decompositions exist.
