Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494308, here are decompositions:

7 + 31494301 = 31494308
61 + 31494247 = 31494308
67 + 31494241 = 31494308
151 + 31494157 = 31494308
211 + 31494097 = 31494308
229 + 31494079 = 31494308
367 + 31493941 = 31494308
409 + 31493899 = 31494308

Showing the first eight; more decompositions exist.
