Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542292, here are decompositions:

11 + 31542281 = 31542292
59 + 31542233 = 31542292
179 + 31542113 = 31542292
269 + 31542023 = 31542292
281 + 31542011 = 31542292
311 + 31541981 = 31542292
359 + 31541933 = 31542292
389 + 31541903 = 31542292

Showing the first eight; more decompositions exist.
