Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448798, here are decompositions:

79 + 31448719 = 31448798
151 + 31448647 = 31448798
211 + 31448587 = 31448798
349 + 31448449 = 31448798
421 + 31448377 = 31448798
499 + 31448299 = 31448798
607 + 31448191 = 31448798
727 + 31448071 = 31448798

Showing the first eight; more decompositions exist.
