Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615196, here are decompositions:

3 + 31615193 = 31615196
43 + 31615153 = 31615196
157 + 31615039 = 31615196
307 + 31614889 = 31615196
337 + 31614859 = 31615196
367 + 31614829 = 31615196
409 + 31614787 = 31615196
463 + 31614733 = 31615196

Showing the first eight; more decompositions exist.
