Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87224, here are decompositions:
- 3 + 87221 = 87224
- 13 + 87211 = 87224
- 37 + 87187 = 87224
- 43 + 87181 = 87224
- 73 + 87151 = 87224
- 103 + 87121 = 87224
- 211 + 87013 = 87224
- 367 + 86857 = 87224
Showing the first eight; more decompositions exist.
