Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126940, here are decompositions:
- 17 + 126923 = 126940
- 83 + 126857 = 126940
- 89 + 126851 = 126940
- 101 + 126839 = 126940
- 113 + 126827 = 126940
- 179 + 126761 = 126940
- 197 + 126743 = 126940
- 227 + 126713 = 126940
Showing the first eight; more decompositions exist.
