Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592224, here are decompositions:

5 + 31592219 = 31592224
11 + 31592213 = 31592224
101 + 31592123 = 31592224
173 + 31592051 = 31592224
227 + 31591997 = 31592224
311 + 31591913 = 31592224
431 + 31591793 = 31592224
491 + 31591733 = 31592224

Showing the first eight; more decompositions exist.
