Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592470, here are decompositions:

3 + 31592467 = 31592470
17 + 31592453 = 31592470
23 + 31592447 = 31592470
47 + 31592423 = 31592470
53 + 31592417 = 31592470
59 + 31592411 = 31592470
101 + 31592369 = 31592470
113 + 31592357 = 31592470

Showing the first eight; more decompositions exist.
