Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463738, here are decompositions:

151 + 31463587 = 31463738
211 + 31463527 = 31463738
331 + 31463407 = 31463738
349 + 31463389 = 31463738
409 + 31463329 = 31463738
421 + 31463317 = 31463738
457 + 31463281 = 31463738
541 + 31463197 = 31463738

Showing the first eight; more decompositions exist.
