Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462710, here are decompositions:

61 + 31462649 = 31462710
101 + 31462609 = 31462710
107 + 31462603 = 31462710
127 + 31462583 = 31462710
131 + 31462579 = 31462710
137 + 31462573 = 31462710
157 + 31462553 = 31462710
163 + 31462547 = 31462710

Showing the first eight; more decompositions exist.
