Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722974, here are decompositions:

5 + 8722969 = 8722974
61 + 8722913 = 8722974
83 + 8722891 = 8722974
97 + 8722877 = 8722974
263 + 8722711 = 8722974
313 + 8722661 = 8722974
331 + 8722643 = 8722974
353 + 8722621 = 8722974

Showing the first eight; more decompositions exist.
