Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99640, here are decompositions:
- 17 + 99623 = 99640
- 29 + 99611 = 99640
- 59 + 99581 = 99640
- 89 + 99551 = 99640
- 113 + 99527 = 99640
- 239 + 99401 = 99640
- 263 + 99377 = 99640
- 269 + 99371 = 99640
Showing the first eight; more decompositions exist.
