Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550882, here are decompositions:

3 + 31550879 = 31550882
31 + 31550851 = 31550882
79 + 31550803 = 31550882
151 + 31550731 = 31550882
211 + 31550671 = 31550882
271 + 31550611 = 31550882
283 + 31550599 = 31550882
313 + 31550569 = 31550882

Showing the first eight; more decompositions exist.
