Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463678, here are decompositions:

151 + 31463527 = 31463678
271 + 31463407 = 31463678
349 + 31463329 = 31463678
397 + 31463281 = 31463678
409 + 31463269 = 31463678
541 + 31463137 = 31463678
601 + 31463077 = 31463678
709 + 31462969 = 31463678

Showing the first eight; more decompositions exist.
