Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615362, here are decompositions:

19 + 31615343 = 31615362
29 + 31615333 = 31615362
41 + 31615321 = 31615362
89 + 31615273 = 31615362
151 + 31615211 = 31615362
193 + 31615169 = 31615362
199 + 31615163 = 31615362
349 + 31615013 = 31615362

Showing the first eight; more decompositions exist.
