Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484070, here are decompositions:

11 + 31484059 = 31484070
89 + 31483981 = 31484070
113 + 31483957 = 31484070
151 + 31483919 = 31484070
157 + 31483913 = 31484070
181 + 31483889 = 31484070
193 + 31483877 = 31484070
199 + 31483871 = 31484070

Showing the first eight; more decompositions exist.
