Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458774, here are decompositions:

13 + 31458761 = 31458774
71 + 31458703 = 31458774
73 + 31458701 = 31458774
107 + 31458667 = 31458774
131 + 31458643 = 31458774
167 + 31458607 = 31458774
173 + 31458601 = 31458774
181 + 31458593 = 31458774

Showing the first eight; more decompositions exist.
