Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638350, here are decompositions:
- 11 + 8638339 = 8638350
- 13 + 8638337 = 8638350
- 23 + 8638327 = 8638350
- 31 + 8638319 = 8638350
- 59 + 8638291 = 8638350
- 67 + 8638283 = 8638350
- 73 + 8638277 = 8638350
- 103 + 8638247 = 8638350
Showing the first eight; more decompositions exist.
