Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620812, here are decompositions:

73 + 8620739 = 8620812
89 + 8620723 = 8620812
139 + 8620673 = 8620812
149 + 8620663 = 8620812
173 + 8620639 = 8620812
181 + 8620631 = 8620812
191 + 8620621 = 8620812
223 + 8620589 = 8620812

Showing the first eight; more decompositions exist.
