Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618604, here are decompositions:

7 + 31618597 = 31618604
37 + 31618567 = 31618604
163 + 31618441 = 31618604
181 + 31618423 = 31618604
307 + 31618297 = 31618604
373 + 31618231 = 31618604
541 + 31618063 = 31618604
547 + 31618057 = 31618604

Showing the first eight; more decompositions exist.
