Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615334, here are decompositions:

13 + 31615321 = 31615334
61 + 31615273 = 31615334
97 + 31615237 = 31615334
181 + 31615153 = 31615334
271 + 31615063 = 31615334
547 + 31614787 = 31615334
601 + 31614733 = 31615334
631 + 31614703 = 31615334

Showing the first eight; more decompositions exist.
