Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618214, here are decompositions:

3 + 31618211 = 31618214
151 + 31618063 = 31618214
157 + 31618057 = 31618214
211 + 31618003 = 31618214
337 + 31617877 = 31618214
457 + 31617757 = 31618214
541 + 31617673 = 31618214
547 + 31617667 = 31618214

Showing the first eight; more decompositions exist.
