Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472330, here are decompositions:

37 + 31472293 = 31472330
139 + 31472191 = 31472330
151 + 31472179 = 31472330
163 + 31472167 = 31472330
181 + 31472149 = 31472330
199 + 31472131 = 31472330
223 + 31472107 = 31472330
277 + 31472053 = 31472330

Showing the first eight; more decompositions exist.
