Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615076, here are decompositions:

13 + 31615063 = 31615076
37 + 31615039 = 31615076
223 + 31614853 = 31615076
307 + 31614769 = 31615076
373 + 31614703 = 31615076
379 + 31614697 = 31615076
433 + 31614643 = 31615076
733 + 31614343 = 31615076

Showing the first eight; more decompositions exist.
