Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699228, here are decompositions:

61 + 8699167 = 8699228
67 + 8699161 = 8699228
151 + 8699077 = 8699228
367 + 8698861 = 8699228
397 + 8698831 = 8699228
409 + 8698819 = 8699228
547 + 8698681 = 8699228
607 + 8698621 = 8699228

Showing the first eight; more decompositions exist.
