Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586126, here are decompositions:

67 + 31586059 = 31586126
73 + 31586053 = 31586126
163 + 31585963 = 31586126
223 + 31585903 = 31586126
277 + 31585849 = 31586126
349 + 31585777 = 31586126
463 + 31585663 = 31586126
547 + 31585579 = 31586126

Showing the first eight; more decompositions exist.
