Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462644, here are decompositions:

41 + 31462603 = 31462644
53 + 31462591 = 31462644
61 + 31462583 = 31462644
67 + 31462577 = 31462644
71 + 31462573 = 31462644
97 + 31462547 = 31462644
113 + 31462531 = 31462644
137 + 31462507 = 31462644

Showing the first eight; more decompositions exist.
