Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618752, here are decompositions:

41 + 31618711 = 31618752
59 + 31618693 = 31618752
71 + 31618681 = 31618752
83 + 31618669 = 31618752
89 + 31618663 = 31618752
131 + 31618621 = 31618752
173 + 31618579 = 31618752
233 + 31618519 = 31618752

Showing the first eight; more decompositions exist.
