Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519610, here are decompositions:

43 + 31519567 = 31519610
79 + 31519531 = 31519610
103 + 31519507 = 31519610
127 + 31519483 = 31519610
151 + 31519459 = 31519610
193 + 31519417 = 31519610
229 + 31519381 = 31519610
313 + 31519297 = 31519610

Showing the first eight; more decompositions exist.
