Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446974, here are decompositions:

37 + 31446937 = 31446974
103 + 31446871 = 31446974
127 + 31446847 = 31446974
367 + 31446607 = 31446974
421 + 31446553 = 31446974
547 + 31446427 = 31446974
607 + 31446367 = 31446974
613 + 31446361 = 31446974

Showing the first eight; more decompositions exist.
