Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642134, here are decompositions:

23 + 8642111 = 8642134
71 + 8642063 = 8642134
101 + 8642033 = 8642134
107 + 8642027 = 8642134
131 + 8642003 = 8642134
251 + 8641883 = 8642134
317 + 8641817 = 8642134
353 + 8641781 = 8642134

Showing the first eight; more decompositions exist.
