Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704642, here are decompositions:

29 + 8704613 = 8704642
41 + 8704601 = 8704642
53 + 8704589 = 8704642
83 + 8704559 = 8704642
239 + 8704403 = 8704642
311 + 8704331 = 8704642
389 + 8704253 = 8704642
449 + 8704193 = 8704642

Showing the first eight; more decompositions exist.
