Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570564, here are decompositions:

  • 83 + 31570481 = 31570564
  • 167 + 31570397 = 31570564
  • 173 + 31570391 = 31570564
  • 191 + 31570373 = 31570564
  • 227 + 31570337 = 31570564
  • 251 + 31570313 = 31570564
  • 353 + 31570211 = 31570564
  • 401 + 31570163 = 31570564

Showing the first eight; more decompositions exist.
