Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462712, here are decompositions:

103 + 31462609 = 31462712
109 + 31462603 = 31462712
139 + 31462573 = 31462712
181 + 31462531 = 31462712
241 + 31462471 = 31462712
271 + 31462441 = 31462712
331 + 31462381 = 31462712
349 + 31462363 = 31462712

Showing the first eight; more decompositions exist.
