Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698180, here are decompositions:

47 + 8698133 = 8698180
59 + 8698121 = 8698180
83 + 8698097 = 8698180
131 + 8698049 = 8698180
233 + 8697947 = 8698180
311 + 8697869 = 8698180
347 + 8697833 = 8698180
383 + 8697797 = 8698180

Showing the first eight; more decompositions exist.
