Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543962, here are decompositions:

59 + 31543903 = 31543962
89 + 31543873 = 31543962
103 + 31543859 = 31543962
179 + 31543783 = 31543962
193 + 31543769 = 31543962
199 + 31543763 = 31543962
211 + 31543751 = 31543962
239 + 31543723 = 31543962

Showing the first eight; more decompositions exist.
