Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494852, here are decompositions:

43 + 31494809 = 31494852
71 + 31494781 = 31494852
83 + 31494769 = 31494852
89 + 31494763 = 31494852
131 + 31494721 = 31494852
139 + 31494713 = 31494852
163 + 31494689 = 31494852
173 + 31494679 = 31494852

Showing the first eight; more decompositions exist.
