Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542502, here are decompositions:

23 + 31542479 = 31542502
83 + 31542419 = 31542502
179 + 31542323 = 31542502
269 + 31542233 = 31542502
353 + 31542149 = 31542502
389 + 31542113 = 31542502
419 + 31542083 = 31542502
479 + 31542023 = 31542502

Showing the first eight; more decompositions exist.
