Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479116, here are decompositions:

43 + 31479073 = 31479116
157 + 31478959 = 31479116
379 + 31478737 = 31479116
397 + 31478719 = 31479116
523 + 31478593 = 31479116
727 + 31478389 = 31479116
829 + 31478287 = 31479116
937 + 31478179 = 31479116

Showing the first eight; more decompositions exist.
