Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5242, here are decompositions:
- 5 + 5237 = 5242
- 11 + 5231 = 5242
- 53 + 5189 = 5242
- 71 + 5171 = 5242
- 89 + 5153 = 5242
- 191 + 5051 = 5242
- 233 + 5009 = 5242
- 239 + 5003 = 5242
Showing the first eight; more decompositions exist.
