Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462716, here are decompositions:

67 + 31462649 = 31462716
107 + 31462609 = 31462716
113 + 31462603 = 31462716
127 + 31462589 = 31462716
137 + 31462579 = 31462716
139 + 31462577 = 31462716
163 + 31462553 = 31462716
277 + 31462439 = 31462716

Showing the first eight; more decompositions exist.
