Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618734, here are decompositions:

23 + 31618711 = 31618734
31 + 31618703 = 31618734
41 + 31618693 = 31618734
53 + 31618681 = 31618734
71 + 31618663 = 31618734
97 + 31618637 = 31618734
101 + 31618633 = 31618734
113 + 31618621 = 31618734

Showing the first eight; more decompositions exist.
