Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615544, here are decompositions:

61 + 31615483 = 31615544
67 + 31615477 = 31615544
73 + 31615471 = 31615544
127 + 31615417 = 31615544
211 + 31615333 = 31615544
223 + 31615321 = 31615544
271 + 31615273 = 31615544
307 + 31615237 = 31615544

Showing the first eight; more decompositions exist.
