Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492374, here are decompositions:

5 + 31492369 = 31492374
37 + 31492337 = 31492374
97 + 31492277 = 31492374
113 + 31492261 = 31492374
131 + 31492243 = 31492374
211 + 31492163 = 31492374
281 + 31492093 = 31492374
283 + 31492091 = 31492374

Showing the first eight; more decompositions exist.
