Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493024, here are decompositions:

7 + 31493017 = 31493024
61 + 31492963 = 31493024
103 + 31492921 = 31493024
223 + 31492801 = 31493024
373 + 31492651 = 31493024
397 + 31492627 = 31493024
421 + 31492603 = 31493024
457 + 31492567 = 31493024

Showing the first eight; more decompositions exist.
