Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449044, here are decompositions:

7 + 31449037 = 31449044
181 + 31448863 = 31449044
223 + 31448821 = 31449044
241 + 31448803 = 31449044
331 + 31448713 = 31449044
337 + 31448707 = 31449044
397 + 31448647 = 31449044
457 + 31448587 = 31449044

Showing the first eight; more decompositions exist.
