Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482418, here are decompositions:

17 + 31482401 = 31482418
29 + 31482389 = 31482418
137 + 31482281 = 31482418
239 + 31482179 = 31482418
251 + 31482167 = 31482418
467 + 31481951 = 31482418
479 + 31481939 = 31482418
587 + 31481831 = 31482418

Showing the first eight; more decompositions exist.
