Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638874, here are decompositions:

7 + 8638867 = 8638874
31 + 8638843 = 8638874
67 + 8638807 = 8638874
241 + 8638633 = 8638874
331 + 8638543 = 8638874
397 + 8638477 = 8638874
421 + 8638453 = 8638874
463 + 8638411 = 8638874

Showing the first eight; more decompositions exist.
