Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449098, here are decompositions:

61 + 31449037 = 31449098
199 + 31448899 = 31449098
277 + 31448821 = 31449098
379 + 31448719 = 31449098
547 + 31448551 = 31449098
619 + 31448479 = 31449098
907 + 31448191 = 31449098
937 + 31448161 = 31449098

Showing the first eight; more decompositions exist.
