Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544342, here are decompositions:

19 + 31544323 = 31544342
31 + 31544311 = 31544342
61 + 31544281 = 31544342
163 + 31544179 = 31544342
211 + 31544131 = 31544342
331 + 31544011 = 31544342
439 + 31543903 = 31544342
499 + 31543843 = 31544342

Showing the first eight; more decompositions exist.
