Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617452, here are decompositions:

3 + 31617449 = 31617452
43 + 31617409 = 31617452
73 + 31617379 = 31617452
79 + 31617373 = 31617452
199 + 31617253 = 31617452
271 + 31617181 = 31617452
379 + 31617073 = 31617452
439 + 31617013 = 31617452

Showing the first eight; more decompositions exist.
