Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618848, here are decompositions:

29 + 31618819 = 31618848
67 + 31618781 = 31618848
71 + 31618777 = 31618848
97 + 31618751 = 31618848
137 + 31618711 = 31618848
167 + 31618681 = 31618848
179 + 31618669 = 31618848
211 + 31618637 = 31618848

Showing the first eight; more decompositions exist.
