Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588524, here are decompositions:

31 + 31588493 = 31588524
41 + 31588483 = 31588524
53 + 31588471 = 31588524
61 + 31588463 = 31588524
83 + 31588441 = 31588524
157 + 31588367 = 31588524
167 + 31588357 = 31588524
173 + 31588351 = 31588524

Showing the first eight; more decompositions exist.
