Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462856, here are decompositions:

97 + 31462759 = 31462856
109 + 31462747 = 31462856
127 + 31462729 = 31462856
277 + 31462579 = 31462856
283 + 31462573 = 31462856
349 + 31462507 = 31462856
499 + 31462357 = 31462856
787 + 31462069 = 31462856

Showing the first eight; more decompositions exist.
