Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982900, here are decompositions:

29 + 982871 = 982900
53 + 982847 = 982900
59 + 982841 = 982900
71 + 982829 = 982900
131 + 982769 = 982900
197 + 982703 = 982900
257 + 982643 = 982900
311 + 982589 = 982900

Showing the first eight; more decompositions exist.
