Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458422, here are decompositions:

3 + 31458419 = 31458422
19 + 31458403 = 31458422
43 + 31458379 = 31458422
409 + 31458013 = 31458422
433 + 31457989 = 31458422
601 + 31457821 = 31458422
811 + 31457611 = 31458422
1039 + 31457383 = 31458422

Showing the first eight; more decompositions exist.
