Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544712, here are decompositions:

139 + 31544573 = 31544712
151 + 31544561 = 31544712
179 + 31544533 = 31544712
181 + 31544531 = 31544712
349 + 31544363 = 31544712
389 + 31544323 = 31544712
401 + 31544311 = 31544712
431 + 31544281 = 31544712

Showing the first eight; more decompositions exist.
