Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449032, here are decompositions:

3 + 31449029 = 31449032
193 + 31448839 = 31449032
211 + 31448821 = 31449032
229 + 31448803 = 31449032
313 + 31448719 = 31449032
499 + 31448533 = 31449032
619 + 31448413 = 31449032
709 + 31448323 = 31449032

Showing the first eight; more decompositions exist.
