Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618696, here are decompositions:

3 + 31618693 = 31618696
59 + 31618637 = 31618696
149 + 31618547 = 31618696
233 + 31618463 = 31618696
293 + 31618403 = 31618696
503 + 31618193 = 31618696
509 + 31618187 = 31618696
563 + 31618133 = 31618696

Showing the first eight; more decompositions exist.
