Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460892, here are decompositions:

13 + 31460879 = 31460892
19 + 31460873 = 31460892
41 + 31460851 = 31460892
53 + 31460839 = 31460892
59 + 31460833 = 31460892
61 + 31460831 = 31460892
83 + 31460809 = 31460892
101 + 31460791 = 31460892

Showing the first eight; more decompositions exist.
