Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468662, here are decompositions:

31 + 31468631 = 31468662
73 + 31468589 = 31468662
89 + 31468573 = 31468662
103 + 31468559 = 31468662
109 + 31468553 = 31468662
139 + 31468523 = 31468662
151 + 31468511 = 31468662
163 + 31468499 = 31468662

Showing the first eight; more decompositions exist.
