Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460802, here are decompositions:

11 + 31460791 = 31460802
19 + 31460783 = 31460802
59 + 31460743 = 31460802
73 + 31460729 = 31460802
101 + 31460701 = 31460802
193 + 31460609 = 31460802
251 + 31460551 = 31460802
293 + 31460509 = 31460802

Showing the first eight; more decompositions exist.
