Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617674, here are decompositions:

7 + 31617667 = 31617674
43 + 31617631 = 31617674
181 + 31617493 = 31617674
271 + 31617403 = 31617674
313 + 31617361 = 31617674
421 + 31617253 = 31617674
541 + 31617133 = 31617674
601 + 31617073 = 31617674

Showing the first eight; more decompositions exist.
