Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458594, here are decompositions:

5 + 31458589 = 31458594
7 + 31458587 = 31458594
53 + 31458541 = 31458594
67 + 31458527 = 31458594
107 + 31458487 = 31458594
113 + 31458481 = 31458594
157 + 31458437 = 31458594
163 + 31458431 = 31458594

Showing the first eight; more decompositions exist.
