Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40188, here are decompositions:
- 11 + 40177 = 40188
- 19 + 40169 = 40188
- 37 + 40151 = 40188
- 59 + 40129 = 40188
- 61 + 40127 = 40188
- 89 + 40099 = 40188
- 101 + 40087 = 40188
- 149 + 40039 = 40188
Showing the first eight; more decompositions exist.
