Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484934, here are decompositions:

23 + 31484911 = 31484934
31 + 31484903 = 31484934
71 + 31484863 = 31484934
97 + 31484837 = 31484934
113 + 31484821 = 31484934
137 + 31484797 = 31484934
157 + 31484777 = 31484934
163 + 31484771 = 31484934

Showing the first eight; more decompositions exist.
