Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592598, here are decompositions:

31 + 31592567 = 31592598
41 + 31592557 = 31592598
47 + 31592551 = 31592598
67 + 31592531 = 31592598
109 + 31592489 = 31592598
131 + 31592467 = 31592598
151 + 31592447 = 31592598
181 + 31592417 = 31592598

Showing the first eight; more decompositions exist.
