Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40200, here are decompositions:
- 7 + 40193 = 40200
- 11 + 40189 = 40200
- 23 + 40177 = 40200
- 31 + 40169 = 40200
- 37 + 40163 = 40200
- 47 + 40153 = 40200
- 71 + 40129 = 40200
- 73 + 40127 = 40200
Showing the first eight; more decompositions exist.
