Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99240, here are decompositions:
- 7 + 99233 = 99240
- 17 + 99223 = 99240
- 59 + 99181 = 99240
- 67 + 99173 = 99240
- 101 + 99139 = 99240
- 103 + 99137 = 99240
- 107 + 99133 = 99240
- 109 + 99131 = 99240
Showing the first eight; more decompositions exist.
