Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592670, here are decompositions:

7 + 31592663 = 31592670
19 + 31592651 = 31592670
29 + 31592641 = 31592670
71 + 31592599 = 31592670
103 + 31592567 = 31592670
113 + 31592557 = 31592670
139 + 31592531 = 31592670
181 + 31592489 = 31592670

Showing the first eight; more decompositions exist.
