Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460668, here are decompositions:

11 + 31460657 = 31460668
59 + 31460609 = 31460668
131 + 31460537 = 31460668
227 + 31460441 = 31460668
269 + 31460399 = 31460668
347 + 31460321 = 31460668
389 + 31460279 = 31460668
401 + 31460267 = 31460668

Showing the first eight; more decompositions exist.
