Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617292, here are decompositions:

11 + 31617281 = 31617292
23 + 31617269 = 31617292
41 + 31617251 = 31617292
53 + 31617239 = 31617292
191 + 31617101 = 31617292
263 + 31617029 = 31617292
269 + 31617023 = 31617292
281 + 31617011 = 31617292

Showing the first eight; more decompositions exist.
