Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460844, here are decompositions:

5 + 31460839 = 31460844
7 + 31460837 = 31460844
11 + 31460833 = 31460844
13 + 31460831 = 31460844
53 + 31460791 = 31460844
61 + 31460783 = 31460844
101 + 31460743 = 31460844
127 + 31460717 = 31460844

Showing the first eight; more decompositions exist.
