Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938998, here are decompositions:

17 + 938981 = 938998
29 + 938969 = 938998
59 + 938939 = 938998
167 + 938831 = 938998
191 + 938807 = 938998
251 + 938747 = 938998
317 + 938681 = 938998
461 + 938537 = 938998

Showing the first eight; more decompositions exist.
