Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458794, here are decompositions:

7 + 31458787 = 31458794
97 + 31458697 = 31458794
127 + 31458667 = 31458794
151 + 31458643 = 31458794
163 + 31458631 = 31458794
193 + 31458601 = 31458794
307 + 31458487 = 31458794
313 + 31458481 = 31458794

Showing the first eight; more decompositions exist.
