Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460742, here are decompositions:

13 + 31460729 = 31460742
41 + 31460701 = 31460742
191 + 31460551 = 31460742
193 + 31460549 = 31460742
233 + 31460509 = 31460742
251 + 31460491 = 31460742
311 + 31460431 = 31460742
373 + 31460369 = 31460742

Showing the first eight; more decompositions exist.
