Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592128, here are decompositions:

5 + 31592123 = 31592128
89 + 31592039 = 31592128
131 + 31591997 = 31592128
149 + 31591979 = 31592128
389 + 31591739 = 31592128
461 + 31591667 = 31592128
479 + 31591649 = 31592128
719 + 31591409 = 31592128

Showing the first eight; more decompositions exist.
