Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493744, here are decompositions:

67 + 31493677 = 31493744
103 + 31493641 = 31493744
151 + 31493593 = 31493744
211 + 31493533 = 31493744
223 + 31493521 = 31493744
277 + 31493467 = 31493744
367 + 31493377 = 31493744
397 + 31493347 = 31493744

Showing the first eight; more decompositions exist.
