Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448546, here are decompositions:

13 + 31448533 = 31448546
67 + 31448479 = 31448546
97 + 31448449 = 31448546
223 + 31448323 = 31448546
313 + 31448233 = 31448546
397 + 31448149 = 31448546
523 + 31448023 = 31448546
643 + 31447903 = 31448546

Showing the first eight; more decompositions exist.
