Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448696, here are decompositions:

3 + 31448693 = 31448696
109 + 31448587 = 31448696
163 + 31448533 = 31448696
283 + 31448413 = 31448696
373 + 31448323 = 31448696
397 + 31448299 = 31448696
463 + 31448233 = 31448696
547 + 31448149 = 31448696

Showing the first eight; more decompositions exist.
