Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615098, here are decompositions:

37 + 31615061 = 31615098
59 + 31615039 = 31615098
157 + 31614941 = 31615098
199 + 31614899 = 31615098
239 + 31614859 = 31615098
269 + 31614829 = 31615098
311 + 31614787 = 31615098
397 + 31614701 = 31615098

Showing the first eight; more decompositions exist.
