Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618846, here are decompositions:

23 + 31618823 = 31618846
383 + 31618463 = 31618846
443 + 31618403 = 31618846
557 + 31618289 = 31618846
647 + 31618199 = 31618846
653 + 31618193 = 31618846
659 + 31618187 = 31618846
683 + 31618163 = 31618846

Showing the first eight; more decompositions exist.
