Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481882, here are decompositions:

31 + 31481851 = 31481882
139 + 31481743 = 31481882
151 + 31481731 = 31481882
181 + 31481701 = 31481882
199 + 31481683 = 31481882
373 + 31481509 = 31481882
409 + 31481473 = 31481882
433 + 31481449 = 31481882

Showing the first eight; more decompositions exist.
