Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448636, here are decompositions:

103 + 31448533 = 31448636
157 + 31448479 = 31448636
223 + 31448413 = 31448636
313 + 31448323 = 31448636
337 + 31448299 = 31448636
487 + 31448149 = 31448636
613 + 31448023 = 31448636
619 + 31448017 = 31448636

Showing the first eight; more decompositions exist.
