Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460746, here are decompositions:

3 + 31460743 = 31460746
17 + 31460729 = 31460746
29 + 31460717 = 31460746
89 + 31460657 = 31460746
137 + 31460609 = 31460746
197 + 31460549 = 31460746
263 + 31460483 = 31460746
347 + 31460399 = 31460746

Showing the first eight; more decompositions exist.
