Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40242, here are decompositions:
- 5 + 40237 = 40242
- 11 + 40231 = 40242
- 29 + 40213 = 40242
- 53 + 40189 = 40242
- 73 + 40169 = 40242
- 79 + 40163 = 40242
- 89 + 40153 = 40242
- 113 + 40129 = 40242
Showing the first eight; more decompositions exist.
