Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462658, here are decompositions:

67 + 31462591 = 31462658
79 + 31462579 = 31462658
127 + 31462531 = 31462658
151 + 31462507 = 31462658
277 + 31462381 = 31462658
307 + 31462351 = 31462658
709 + 31461949 = 31462658
739 + 31461919 = 31462658

Showing the first eight; more decompositions exist.
