Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40140, here are decompositions:
- 11 + 40129 = 40140
- 13 + 40127 = 40140
- 17 + 40123 = 40140
- 29 + 40111 = 40140
- 41 + 40099 = 40140
- 47 + 40093 = 40140
- 53 + 40087 = 40140
- 101 + 40039 = 40140
Showing the first eight; more decompositions exist.
