Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709078, here are decompositions:

11 + 8709067 = 8709078
19 + 8709059 = 8709078
71 + 8709007 = 8709078
107 + 8708971 = 8709078
109 + 8708969 = 8709078
167 + 8708911 = 8709078
229 + 8708849 = 8709078
271 + 8708807 = 8709078

Showing the first eight; more decompositions exist.
