Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462838, here are decompositions:

7 + 31462831 = 31462838
31 + 31462807 = 31462838
67 + 31462771 = 31462838
79 + 31462759 = 31462838
109 + 31462729 = 31462838
229 + 31462609 = 31462838
307 + 31462531 = 31462838
331 + 31462507 = 31462838

Showing the first eight; more decompositions exist.
