Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613282, here are decompositions:

139 + 31613143 = 31613282
163 + 31613119 = 31613282
229 + 31613053 = 31613282
313 + 31612969 = 31613282
331 + 31612951 = 31613282
409 + 31612873 = 31613282
523 + 31612759 = 31613282
619 + 31612663 = 31613282

Showing the first eight; more decompositions exist.
