Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458600, here are decompositions:

7 + 31458593 = 31458600
11 + 31458589 = 31458600
13 + 31458587 = 31458600
59 + 31458541 = 31458600
73 + 31458527 = 31458600
113 + 31458487 = 31458600
149 + 31458451 = 31458600
163 + 31458437 = 31458600

Showing the first eight; more decompositions exist.
