Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87418, here are decompositions:
- 11 + 87407 = 87418
- 59 + 87359 = 87418
- 101 + 87317 = 87418
- 137 + 87281 = 87418
- 167 + 87251 = 87418
- 197 + 87221 = 87418
- 239 + 87179 = 87418
- 269 + 87149 = 87418
Showing the first eight; more decompositions exist.
