Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467746, here are decompositions:

19 + 31467727 = 31467746
157 + 31467589 = 31467746
313 + 31467433 = 31467746
379 + 31467367 = 31467746
487 + 31467259 = 31467746
547 + 31467199 = 31467746
577 + 31467169 = 31467746
613 + 31467133 = 31467746

Showing the first eight; more decompositions exist.
