Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749180, here are decompositions:

17 + 8749163 = 8749180
29 + 8749151 = 8749180
47 + 8749133 = 8749180
53 + 8749127 = 8749180
59 + 8749121 = 8749180
131 + 8749049 = 8749180
173 + 8749007 = 8749180
179 + 8749001 = 8749180

Showing the first eight; more decompositions exist.
