Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460556, here are decompositions:

5 + 31460551 = 31460556
7 + 31460549 = 31460556
19 + 31460537 = 31460556
47 + 31460509 = 31460556
59 + 31460497 = 31460556
73 + 31460483 = 31460556
157 + 31460399 = 31460556
227 + 31460329 = 31460556

Showing the first eight; more decompositions exist.
