Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726442, here are decompositions:

41 + 8726401 = 8726442
59 + 8726383 = 8726442
61 + 8726381 = 8726442
79 + 8726363 = 8726442
83 + 8726359 = 8726442
113 + 8726329 = 8726442
199 + 8726243 = 8726442
233 + 8726209 = 8726442

Showing the first eight; more decompositions exist.
