Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448410, here are decompositions:

29 + 31448381 = 31448410
41 + 31448369 = 31448410
89 + 31448321 = 31448410
101 + 31448309 = 31448410
107 + 31448303 = 31448410
113 + 31448297 = 31448410
239 + 31448171 = 31448410
269 + 31448141 = 31448410

Showing the first eight; more decompositions exist.
