Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619172, here are decompositions:

5 + 8619167 = 8619172
41 + 8619131 = 8619172
71 + 8619101 = 8619172
101 + 8619071 = 8619172
113 + 8619059 = 8619172
131 + 8619041 = 8619172
173 + 8618999 = 8619172
239 + 8618933 = 8619172

Showing the first eight; more decompositions exist.
