Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480832, here are decompositions:

3 + 31480829 = 31480832
139 + 31480693 = 31480832
151 + 31480681 = 31480832
193 + 31480639 = 31480832
211 + 31480621 = 31480832
463 + 31480369 = 31480832
631 + 31480201 = 31480832
811 + 31480021 = 31480832

Showing the first eight; more decompositions exist.
