Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4236, here are decompositions:
- 5 + 4231 = 4236
- 7 + 4229 = 4236
- 17 + 4219 = 4236
- 19 + 4217 = 4236
- 59 + 4177 = 4236
- 79 + 4157 = 4236
- 83 + 4153 = 4236
- 97 + 4139 = 4236
Showing the first eight; more decompositions exist.
