Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615292, here are decompositions:

19 + 31615273 = 31615292
139 + 31615153 = 31615292
229 + 31615063 = 31615292
349 + 31614943 = 31615292
433 + 31614859 = 31615292
439 + 31614853 = 31615292
463 + 31614829 = 31615292
523 + 31614769 = 31615292

Showing the first eight; more decompositions exist.
