Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699872, here are decompositions:

59 + 8699813 = 8699872
101 + 8699771 = 8699872
149 + 8699723 = 8699872
239 + 8699633 = 8699872
353 + 8699519 = 8699872
359 + 8699513 = 8699872
383 + 8699489 = 8699872
449 + 8699423 = 8699872

Showing the first eight; more decompositions exist.
