Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449176, here are decompositions:

13 + 31449163 = 31449176
139 + 31449037 = 31449176
277 + 31448899 = 31449176
313 + 31448863 = 31449176
337 + 31448839 = 31449176
373 + 31448803 = 31449176
457 + 31448719 = 31449176
463 + 31448713 = 31449176

Showing the first eight; more decompositions exist.
