Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541324, here are decompositions:

43 + 31541281 = 31541324
151 + 31541173 = 31541324
163 + 31541161 = 31541324
211 + 31541113 = 31541324
223 + 31541101 = 31541324
277 + 31541047 = 31541324
307 + 31541017 = 31541324
457 + 31540867 = 31541324

Showing the first eight; more decompositions exist.
