Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127008, here are decompositions:
- 19 + 126989 = 127008
- 41 + 126967 = 127008
- 47 + 126961 = 127008
- 59 + 126949 = 127008
- 149 + 126859 = 127008
- 151 + 126857 = 127008
- 157 + 126851 = 127008
- 181 + 126827 = 127008
Showing the first eight; more decompositions exist.
