Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55224, here are decompositions:
- 5 + 55219 = 55224
- 7 + 55217 = 55224
- 11 + 55213 = 55224
- 17 + 55207 = 55224
- 23 + 55201 = 55224
- 53 + 55171 = 55224
- 61 + 55163 = 55224
- 97 + 55127 = 55224
Showing the first eight; more decompositions exist.
