Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724180, here are decompositions:

11 + 8724169 = 8724180
19 + 8724161 = 8724180
37 + 8724143 = 8724180
41 + 8724139 = 8724180
53 + 8724127 = 8724180
79 + 8724101 = 8724180
107 + 8724073 = 8724180
109 + 8724071 = 8724180

Showing the first eight; more decompositions exist.
