Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448924, here are decompositions:

61 + 31448863 = 31448924
103 + 31448821 = 31448924
211 + 31448713 = 31448924
277 + 31448647 = 31448924
337 + 31448587 = 31448924
373 + 31448551 = 31448924
547 + 31448377 = 31448924
601 + 31448323 = 31448924

Showing the first eight; more decompositions exist.
