Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484274, here are decompositions:

7 + 31484267 = 31484274
37 + 31484237 = 31484274
67 + 31484207 = 31484274
71 + 31484203 = 31484274
97 + 31484177 = 31484274
113 + 31484161 = 31484274
131 + 31484143 = 31484274
181 + 31484093 = 31484274

Showing the first eight; more decompositions exist.
