Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542262, here are decompositions:

29 + 31542233 = 31542262
113 + 31542149 = 31542262
149 + 31542113 = 31542262
179 + 31542083 = 31542262
239 + 31542023 = 31542262
251 + 31542011 = 31542262
281 + 31541981 = 31542262
359 + 31541903 = 31542262

Showing the first eight; more decompositions exist.
