Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577694, here are decompositions:

37 + 31577657 = 31577694
47 + 31577647 = 31577694
61 + 31577633 = 31577694
101 + 31577593 = 31577694
103 + 31577591 = 31577694
107 + 31577587 = 31577694
163 + 31577531 = 31577694
167 + 31577527 = 31577694

Showing the first eight; more decompositions exist.
