Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456106, here are decompositions:

7 + 31456099 = 31456106
13 + 31456093 = 31456106
103 + 31456003 = 31456106
229 + 31455877 = 31456106
277 + 31455829 = 31456106
379 + 31455727 = 31456106
457 + 31455649 = 31456106
607 + 31455499 = 31456106

Showing the first eight; more decompositions exist.
