Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493954, here are decompositions:

3 + 31493951 = 31493954
13 + 31493941 = 31493954
73 + 31493881 = 31493954
97 + 31493857 = 31493954
103 + 31493851 = 31493954
211 + 31493743 = 31493954
277 + 31493677 = 31493954
313 + 31493641 = 31493954

Showing the first eight; more decompositions exist.
