Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975780, here are decompositions:
- 23 + 4294975757 = 4294975780
- 41 + 4294975739 = 4294975780
- 47 + 4294975733 = 4294975780
- 83 + 4294975697 = 4294975780
- 107 + 4294975673 = 4294975780
- 131 + 4294975649 = 4294975780
- 191 + 4294975589 = 4294975780
- 233 + 4294975547 = 4294975780
Showing the first eight; more decompositions exist.
