Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448758, here are decompositions:

17 + 31448741 = 31448758
41 + 31448717 = 31448758
59 + 31448699 = 31448758
137 + 31448621 = 31448758
179 + 31448579 = 31448758
239 + 31448519 = 31448758
251 + 31448507 = 31448758
311 + 31448447 = 31448758

Showing the first eight; more decompositions exist.
