Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458484, here are decompositions:

3 + 31458481 = 31458484
47 + 31458437 = 31458484
53 + 31458431 = 31458484
107 + 31458377 = 31458484
173 + 31458311 = 31458484
293 + 31458191 = 31458484
311 + 31458173 = 31458484
353 + 31458131 = 31458484

Showing the first eight; more decompositions exist.
