Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468262, here are decompositions:

3 + 31468259 = 31468262
19 + 31468243 = 31468262
31 + 31468231 = 31468262
61 + 31468201 = 31468262
103 + 31468159 = 31468262
313 + 31467949 = 31468262
409 + 31467853 = 31468262
433 + 31467829 = 31468262

Showing the first eight; more decompositions exist.
