Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724406, here are decompositions:

29 + 8724377 = 8724406
59 + 8724347 = 8724406
83 + 8724323 = 8724406
113 + 8724293 = 8724406
137 + 8724269 = 8724406
263 + 8724143 = 8724406
419 + 8723987 = 8724406
503 + 8723903 = 8724406

Showing the first eight; more decompositions exist.
