Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294968978, here are decompositions:
- 29 + 4294968949 = 4294968978
- 101 + 4294968877 = 4294968978
- 109 + 4294968869 = 4294968978
- 151 + 4294968827 = 4294968978
- 211 + 4294968767 = 4294968978
- 239 + 4294968739 = 4294968978
- 281 + 4294968697 = 4294968978
- 457 + 4294968521 = 4294968978
Showing the first eight; more decompositions exist.
