Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618996, here are decompositions:

5 + 31618991 = 31618996
47 + 31618949 = 31618996
53 + 31618943 = 31618996
113 + 31618883 = 31618996
173 + 31618823 = 31618996
293 + 31618703 = 31618996
359 + 31618637 = 31618996
449 + 31618547 = 31618996

Showing the first eight; more decompositions exist.
