Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448676, here are decompositions:

29 + 31448647 = 31448676
37 + 31448639 = 31448676
73 + 31448603 = 31448676
89 + 31448587 = 31448676
97 + 31448579 = 31448676
157 + 31448519 = 31448676
197 + 31448479 = 31448676
227 + 31448449 = 31448676

Showing the first eight; more decompositions exist.
