Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489652, here are decompositions:

163 + 31489489 = 31489652
241 + 31489411 = 31489652
373 + 31489279 = 31489652
409 + 31489243 = 31489652
643 + 31489009 = 31489652
661 + 31488991 = 31489652
673 + 31488979 = 31489652
853 + 31488799 = 31489652

Showing the first eight; more decompositions exist.
