Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458510, here are decompositions:

23 + 31458487 = 31458510
29 + 31458481 = 31458510
59 + 31458451 = 31458510
73 + 31458437 = 31458510
79 + 31458431 = 31458510
107 + 31458403 = 31458510
131 + 31458379 = 31458510
137 + 31458373 = 31458510

Showing the first eight; more decompositions exist.
