Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99440, here are decompositions:
- 31 + 99409 = 99440
- 43 + 99397 = 99440
- 73 + 99367 = 99440
- 151 + 99289 = 99440
- 163 + 99277 = 99440
- 181 + 99259 = 99440
- 199 + 99241 = 99440
- 307 + 99133 = 99440
Showing the first eight; more decompositions exist.
