Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471662, here are decompositions:

23 + 31471639 = 31471662
29 + 31471633 = 31471662
41 + 31471621 = 31471662
71 + 31471591 = 31471662
83 + 31471579 = 31471662
113 + 31471549 = 31471662
139 + 31471523 = 31471662
151 + 31471511 = 31471662

Showing the first eight; more decompositions exist.
