Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179100, here are decompositions:

11 + 179089 = 179100
17 + 179083 = 179100
43 + 179057 = 179100
59 + 179041 = 179100
67 + 179033 = 179100
71 + 179029 = 179100
79 + 179021 = 179100
113 + 178987 = 179100

Showing the first eight; more decompositions exist.
