Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542534, here are decompositions:

11 + 31542523 = 31542534
47 + 31542487 = 31542534
97 + 31542437 = 31542534
137 + 31542397 = 31542534
157 + 31542377 = 31542534
193 + 31542341 = 31542534
211 + 31542323 = 31542534
337 + 31542197 = 31542534

Showing the first eight; more decompositions exist.
