Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494882, here are decompositions:

73 + 31494809 = 31494882
101 + 31494781 = 31494882
113 + 31494769 = 31494882
191 + 31494691 = 31494882
193 + 31494689 = 31494882
239 + 31494643 = 31494882
271 + 31494611 = 31494882
373 + 31494509 = 31494882

Showing the first eight; more decompositions exist.
