Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628940, here are decompositions:

3 + 8628937 = 8628940
17 + 8628923 = 8628940
41 + 8628899 = 8628940
83 + 8628857 = 8628940
149 + 8628791 = 8628940
167 + 8628773 = 8628940
263 + 8628677 = 8628940
293 + 8628647 = 8628940

Showing the first eight; more decompositions exist.
