Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592604, here are decompositions:

5 + 31592599 = 31592604
37 + 31592567 = 31592604
47 + 31592557 = 31592604
53 + 31592551 = 31592604
73 + 31592531 = 31592604
137 + 31592467 = 31592604
151 + 31592453 = 31592604
157 + 31592447 = 31592604

Showing the first eight; more decompositions exist.
