Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493446, here are decompositions:

3 + 31493443 = 31493446
107 + 31493339 = 31493446
197 + 31493249 = 31493446
293 + 31493153 = 31493446
389 + 31493057 = 31493446
449 + 31492997 = 31493446
503 + 31492943 = 31493446
587 + 31492859 = 31493446

Showing the first eight; more decompositions exist.
