Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468502, here are decompositions:

3 + 31468499 = 31468502
31 + 31468471 = 31468502
103 + 31468399 = 31468502
271 + 31468231 = 31468502
673 + 31467829 = 31468502
691 + 31467811 = 31468502
739 + 31467763 = 31468502
811 + 31467691 = 31468502

Showing the first eight; more decompositions exist.
