Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449026, here are decompositions:

127 + 31448899 = 31449026
163 + 31448863 = 31449026
223 + 31448803 = 31449026
307 + 31448719 = 31449026
313 + 31448713 = 31449026
379 + 31448647 = 31449026
439 + 31448587 = 31449026
547 + 31448479 = 31449026

Showing the first eight; more decompositions exist.
