Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615484, here are decompositions:

7 + 31615477 = 31615484
13 + 31615471 = 31615484
67 + 31615417 = 31615484
151 + 31615333 = 31615484
163 + 31615321 = 31615484
211 + 31615273 = 31615484
331 + 31615153 = 31615484
421 + 31615063 = 31615484

Showing the first eight; more decompositions exist.
