Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493546, here are decompositions:

13 + 31493533 = 31493546
79 + 31493467 = 31493546
103 + 31493443 = 31493546
127 + 31493419 = 31493546
193 + 31493353 = 31493546
199 + 31493347 = 31493546
223 + 31493323 = 31493546
463 + 31493083 = 31493546

Showing the first eight; more decompositions exist.
