Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618792, here are decompositions:

11 + 31618781 = 31618792
41 + 31618751 = 31618792
89 + 31618703 = 31618792
383 + 31618409 = 31618792
389 + 31618403 = 31618792
431 + 31618361 = 31618792
503 + 31618289 = 31618792
593 + 31618199 = 31618792

Showing the first eight; more decompositions exist.
