Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724460, here are decompositions:

23 + 8724437 = 8724460
83 + 8724377 = 8724460
89 + 8724371 = 8724460
113 + 8724347 = 8724460
131 + 8724329 = 8724460
137 + 8724323 = 8724460
149 + 8724311 = 8724460
167 + 8724293 = 8724460

Showing the first eight; more decompositions exist.
