Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722746, here are decompositions:

7 + 8722739 = 8722746
73 + 8722673 = 8722746
103 + 8722643 = 8722746
139 + 8722607 = 8722746
229 + 8722517 = 8722746
269 + 8722477 = 8722746
317 + 8722429 = 8722746
337 + 8722409 = 8722746

Showing the first eight; more decompositions exist.
