Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448516, here are decompositions:

37 + 31448479 = 31448516
67 + 31448449 = 31448516
103 + 31448413 = 31448516
139 + 31448377 = 31448516
193 + 31448323 = 31448516
223 + 31448293 = 31448516
283 + 31448233 = 31448516
367 + 31448149 = 31448516

Showing the first eight; more decompositions exist.
