Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724472, here are decompositions:

5 + 8724467 = 8724472
11 + 8724461 = 8724472
101 + 8724371 = 8724472
149 + 8724323 = 8724472
179 + 8724293 = 8724472
311 + 8724161 = 8724472
401 + 8724071 = 8724472
479 + 8723993 = 8724472

Showing the first eight; more decompositions exist.
