Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739186, here are decompositions:

17 + 8739169 = 8739186
19 + 8739167 = 8739186
23 + 8739163 = 8739186
59 + 8739127 = 8739186
67 + 8739119 = 8739186
73 + 8739113 = 8739186
89 + 8739097 = 8739186
107 + 8739079 = 8739186

Showing the first eight; more decompositions exist.
