Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448510, here are decompositions:

3 + 31448507 = 31448510
31 + 31448479 = 31448510
61 + 31448449 = 31448510
97 + 31448413 = 31448510
211 + 31448299 = 31448510
229 + 31448281 = 31448510
277 + 31448233 = 31448510
349 + 31448161 = 31448510

Showing the first eight; more decompositions exist.
