Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722798, here are decompositions:

41 + 8722757 = 8722798
59 + 8722739 = 8722798
137 + 8722661 = 8722798
167 + 8722631 = 8722798
191 + 8722607 = 8722798
257 + 8722541 = 8722798
281 + 8722517 = 8722798
389 + 8722409 = 8722798

Showing the first eight; more decompositions exist.
