Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618876, here are decompositions:

5 + 31618871 = 31618876
53 + 31618823 = 31618876
173 + 31618703 = 31618876
239 + 31618637 = 31618876
467 + 31618409 = 31618876
557 + 31618319 = 31618876
587 + 31618289 = 31618876
677 + 31618199 = 31618876

Showing the first eight; more decompositions exist.
