Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460882, here are decompositions:

3 + 31460879 = 31460882
31 + 31460851 = 31460882
43 + 31460839 = 31460882
73 + 31460809 = 31460882
139 + 31460743 = 31460882
181 + 31460701 = 31460882
331 + 31460551 = 31460882
373 + 31460509 = 31460882

Showing the first eight; more decompositions exist.
