Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460846, here are decompositions:

7 + 31460839 = 31460846
13 + 31460833 = 31460846
37 + 31460809 = 31460846
103 + 31460743 = 31460846
199 + 31460647 = 31460846
337 + 31460509 = 31460846
349 + 31460497 = 31460846
433 + 31460413 = 31460846

Showing the first eight; more decompositions exist.
