Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87586, here are decompositions:
- 3 + 87583 = 87586
- 29 + 87557 = 87586
- 47 + 87539 = 87586
- 113 + 87473 = 87586
- 179 + 87407 = 87586
- 227 + 87359 = 87586
- 263 + 87323 = 87586
- 269 + 87317 = 87586
Showing the first eight; more decompositions exist.
