Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618036, here are decompositions:

83 + 31617953 = 31618036
137 + 31617899 = 31618036
173 + 31617863 = 31618036
239 + 31617797 = 31618036
347 + 31617689 = 31618036
449 + 31617587 = 31618036
503 + 31617533 = 31618036
587 + 31617449 = 31618036

Showing the first eight; more decompositions exist.
