Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471692, here are decompositions:

11 + 31471681 = 31471692
29 + 31471663 = 31471692
53 + 31471639 = 31471692
59 + 31471633 = 31471692
71 + 31471621 = 31471692
101 + 31471591 = 31471692
113 + 31471579 = 31471692
181 + 31471511 = 31471692

Showing the first eight; more decompositions exist.
