Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542484, here are decompositions:

5 + 31542479 = 31542484
47 + 31542437 = 31542484
107 + 31542377 = 31542484
251 + 31542233 = 31542484
401 + 31542083 = 31542484
461 + 31542023 = 31542484
503 + 31541981 = 31542484
593 + 31541891 = 31542484

Showing the first eight; more decompositions exist.
