Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460562, here are decompositions:

11 + 31460551 = 31460562
13 + 31460549 = 31460562
53 + 31460509 = 31460562
71 + 31460491 = 31460562
79 + 31460483 = 31460562
131 + 31460431 = 31460562
149 + 31460413 = 31460562
163 + 31460399 = 31460562

Showing the first eight; more decompositions exist.
