Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544374, here are decompositions:

3 + 31544371 = 31544374
11 + 31544363 = 31544374
167 + 31544207 = 31544374
317 + 31544057 = 31544374
353 + 31544021 = 31544374
383 + 31543991 = 31544374
461 + 31543913 = 31544374
467 + 31543907 = 31544374

Showing the first eight; more decompositions exist.
