Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672438, here are decompositions:
- 31 + 8672407 = 8672438
- 199 + 8672239 = 8672438
- 277 + 8672161 = 8672438
- 337 + 8672101 = 8672438
- 457 + 8671981 = 8672438
- 601 + 8671837 = 8672438
- 727 + 8671711 = 8672438
- 769 + 8671669 = 8672438
Showing the first eight; more decompositions exist.
