Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613248, here are decompositions:

5 + 31613243 = 31613248
131 + 31613117 = 31613248
257 + 31612991 = 31613248
509 + 31612739 = 31613248
521 + 31612727 = 31613248
587 + 31612661 = 31613248
659 + 31612589 = 31613248
701 + 31612547 = 31613248

Showing the first eight; more decompositions exist.
