Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722418, here are decompositions:

79 + 8722339 = 8722418
127 + 8722291 = 8722418
181 + 8722237 = 8722418
337 + 8722081 = 8722418
409 + 8722009 = 8722418
421 + 8721997 = 8722418
541 + 8721877 = 8722418
751 + 8721667 = 8722418

Showing the first eight; more decompositions exist.
