Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618754, here are decompositions:

3 + 31618751 = 31618754
43 + 31618711 = 31618754
61 + 31618693 = 31618754
73 + 31618681 = 31618754
157 + 31618597 = 31618754
313 + 31618441 = 31618754
331 + 31618423 = 31618754
457 + 31618297 = 31618754

Showing the first eight; more decompositions exist.
