Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448508, here are decompositions:

29 + 31448479 = 31448508
59 + 31448449 = 31448508
61 + 31448447 = 31448508
127 + 31448381 = 31448508
131 + 31448377 = 31448508
139 + 31448369 = 31448508
199 + 31448309 = 31448508
211 + 31448297 = 31448508

Showing the first eight; more decompositions exist.
