Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514758, here are decompositions:

17 + 31514741 = 31514758
71 + 31514687 = 31514758
131 + 31514627 = 31514758
179 + 31514579 = 31514758
281 + 31514477 = 31514758
449 + 31514309 = 31514758
461 + 31514297 = 31514758
467 + 31514291 = 31514758

Showing the first eight; more decompositions exist.
