Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460890, here are decompositions:

11 + 31460879 = 31460890
17 + 31460873 = 31460890
53 + 31460837 = 31460890
59 + 31460831 = 31460890
107 + 31460783 = 31460890
173 + 31460717 = 31460890
233 + 31460657 = 31460890
281 + 31460609 = 31460890

Showing the first eight; more decompositions exist.
