Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99742, here are decompositions:
- 23 + 99719 = 99742
- 29 + 99713 = 99742
- 53 + 99689 = 99742
- 131 + 99611 = 99742
- 179 + 99563 = 99742
- 191 + 99551 = 99742
- 311 + 99431 = 99742
- 491 + 99251 = 99742
Showing the first eight; more decompositions exist.
