Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672472, here are decompositions:
- 31 + 8672441 = 8672472
- 43 + 8672429 = 8672472
- 139 + 8672333 = 8672472
- 199 + 8672273 = 8672472
- 233 + 8672239 = 8672472
- 269 + 8672203 = 8672472
- 271 + 8672201 = 8672472
- 311 + 8672161 = 8672472
Showing the first eight; more decompositions exist.
