Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617146, here are decompositions:

13 + 31617133 = 31617146
73 + 31617073 = 31617146
97 + 31617049 = 31617146
229 + 31616917 = 31617146
307 + 31616839 = 31617146
373 + 31616773 = 31617146
397 + 31616749 = 31617146
439 + 31616707 = 31617146

Showing the first eight; more decompositions exist.
