Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673140, here are decompositions:

13 + 8673127 = 8673140
19 + 8673121 = 8673140
31 + 8673109 = 8673140
43 + 8673097 = 8673140
67 + 8673073 = 8673140
103 + 8673037 = 8673140
193 + 8672947 = 8673140
271 + 8672869 = 8673140

Showing the first eight; more decompositions exist.
