Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468208, here are decompositions:

7 + 31468201 = 31468208
61 + 31468147 = 31468208
181 + 31468027 = 31468208
241 + 31467967 = 31468208
271 + 31467937 = 31468208
379 + 31467829 = 31468208
397 + 31467811 = 31468208
487 + 31467721 = 31468208

Showing the first eight; more decompositions exist.
