Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615162, here are decompositions:

53 + 31615109 = 31615162
101 + 31615061 = 31615162
149 + 31615013 = 31615162
233 + 31614929 = 31615162
263 + 31614899 = 31615162
281 + 31614881 = 31615162
311 + 31614851 = 31615162
461 + 31614701 = 31615162

Showing the first eight; more decompositions exist.
