Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473194, here are decompositions:

  • 3 + 31473191 = 31473194
  • 7 + 31473187 = 31473194
  • 31 + 31473163 = 31473194
  • 43 + 31473151 = 31473194
  • 127 + 31473067 = 31473194
  • 157 + 31473037 = 31473194
  • 163 + 31473031 = 31473194
  • 211 + 31472983 = 31473194

Showing the first eight; more decompositions exist.
