Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458504, here are decompositions:

17 + 31458487 = 31458504
23 + 31458481 = 31458504
53 + 31458451 = 31458504
67 + 31458437 = 31458504
73 + 31458431 = 31458504
101 + 31458403 = 31458504
127 + 31458377 = 31458504
131 + 31458373 = 31458504

Showing the first eight; more decompositions exist.
