Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40972, here are decompositions:
- 11 + 40961 = 40972
- 23 + 40949 = 40972
- 89 + 40883 = 40972
- 131 + 40841 = 40972
- 149 + 40823 = 40972
- 233 + 40739 = 40972
- 263 + 40709 = 40972
- 389 + 40583 = 40972
Showing the first eight; more decompositions exist.
