Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460850, here are decompositions:

11 + 31460839 = 31460850
13 + 31460837 = 31460850
17 + 31460833 = 31460850
19 + 31460831 = 31460850
41 + 31460809 = 31460850
59 + 31460791 = 31460850
67 + 31460783 = 31460850
107 + 31460743 = 31460850

Showing the first eight; more decompositions exist.
