Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493374, here are decompositions:

53 + 31493321 = 31493374
83 + 31493291 = 31493374
173 + 31493201 = 31493374
317 + 31493057 = 31493374
383 + 31492991 = 31493374
431 + 31492943 = 31493374
467 + 31492907 = 31493374
593 + 31492781 = 31493374

Showing the first eight; more decompositions exist.
