Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40902, here are decompositions:
- 5 + 40897 = 40902
- 19 + 40883 = 40902
- 23 + 40879 = 40902
- 53 + 40849 = 40902
- 61 + 40841 = 40902
- 73 + 40829 = 40902
- 79 + 40823 = 40902
- 83 + 40819 = 40902
Showing the first eight; more decompositions exist.
