Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480002, here are decompositions:

41 + 31479961 = 31480002
53 + 31479949 = 31480002
173 + 31479829 = 31480002
181 + 31479821 = 31480002
199 + 31479803 = 31480002
233 + 31479769 = 31480002
263 + 31479739 = 31480002
283 + 31479719 = 31480002

Showing the first eight; more decompositions exist.
