Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615352, here are decompositions:

19 + 31615333 = 31615352
31 + 31615321 = 31615352
79 + 31615273 = 31615352
199 + 31615153 = 31615352
313 + 31615039 = 31615352
409 + 31614943 = 31615352
463 + 31614889 = 31615352
499 + 31614853 = 31615352

Showing the first eight; more decompositions exist.
