Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478846, here are decompositions:

109 + 31478737 = 31478846
127 + 31478719 = 31478846
199 + 31478647 = 31478846
367 + 31478479 = 31478846
457 + 31478389 = 31478846
523 + 31478323 = 31478846
673 + 31478173 = 31478846
757 + 31478089 = 31478846

Showing the first eight; more decompositions exist.
