Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462958, here are decompositions:

61 + 31462897 = 31462958
127 + 31462831 = 31462958
151 + 31462807 = 31462958
199 + 31462759 = 31462958
211 + 31462747 = 31462958
229 + 31462729 = 31462958
349 + 31462609 = 31462958
367 + 31462591 = 31462958

Showing the first eight; more decompositions exist.
