Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40878, here are decompositions:
- 11 + 40867 = 40878
- 29 + 40849 = 40878
- 31 + 40847 = 40878
- 37 + 40841 = 40878
- 59 + 40819 = 40878
- 107 + 40771 = 40878
- 127 + 40751 = 40878
- 139 + 40739 = 40878
Showing the first eight; more decompositions exist.
