Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31670, here are decompositions:

3 + 31667 = 31670
7 + 31663 = 31670
13 + 31657 = 31670
43 + 31627 = 31670
97 + 31573 = 31670
103 + 31567 = 31670
127 + 31543 = 31670
139 + 31531 = 31670

Showing the first eight; more decompositions exist.
