Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615282, here are decompositions:

53 + 31615229 = 31615282
71 + 31615211 = 31615282
89 + 31615193 = 31615282
113 + 31615169 = 31615282
173 + 31615109 = 31615282
269 + 31615013 = 31615282
353 + 31614929 = 31615282
383 + 31614899 = 31615282

Showing the first eight; more decompositions exist.
