Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462734, here are decompositions:

5 + 31462729 = 31462734
11 + 31462723 = 31462734
131 + 31462603 = 31462734
151 + 31462583 = 31462734
157 + 31462577 = 31462734
181 + 31462553 = 31462734
227 + 31462507 = 31462734
263 + 31462471 = 31462734

Showing the first eight; more decompositions exist.
