Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448948, here are decompositions:

109 + 31448839 = 31448948
127 + 31448821 = 31448948
229 + 31448719 = 31448948
241 + 31448707 = 31448948
367 + 31448581 = 31448948
397 + 31448551 = 31448948
499 + 31448449 = 31448948
571 + 31448377 = 31448948

Showing the first eight; more decompositions exist.
