Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724436, here are decompositions:

59 + 8724377 = 8724436
89 + 8724347 = 8724436
107 + 8724329 = 8724436
113 + 8724323 = 8724436
167 + 8724269 = 8724436
173 + 8724263 = 8724436
293 + 8724143 = 8724436
443 + 8723993 = 8724436

Showing the first eight; more decompositions exist.
