Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460770, here are decompositions:

41 + 31460729 = 31460770
53 + 31460717 = 31460770
113 + 31460657 = 31460770
233 + 31460537 = 31460770
401 + 31460369 = 31460770
431 + 31460339 = 31460770
449 + 31460321 = 31460770
479 + 31460291 = 31460770

Showing the first eight; more decompositions exist.
