Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449374, here are decompositions:

13 + 31449361 = 31449374
127 + 31449247 = 31449374
211 + 31449163 = 31449374
331 + 31449043 = 31449374
337 + 31449037 = 31449374
571 + 31448803 = 31449374
661 + 31448713 = 31449374
727 + 31448647 = 31449374

Showing the first eight; more decompositions exist.
