Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462496, here are decompositions:

139 + 31462357 = 31462496
157 + 31462339 = 31462496
223 + 31462273 = 31462496
229 + 31462267 = 31462496
547 + 31461949 = 31462496
577 + 31461919 = 31462496
673 + 31461823 = 31462496
733 + 31461763 = 31462496

Showing the first eight; more decompositions exist.
