Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690748, here are decompositions:

7 + 8690741 = 8690748
71 + 8690677 = 8690748
89 + 8690659 = 8690748
109 + 8690639 = 8690748
137 + 8690611 = 8690748
149 + 8690599 = 8690748
181 + 8690567 = 8690748
191 + 8690557 = 8690748

Showing the first eight; more decompositions exist.
