Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47772, here are decompositions:
- 29 + 47743 = 47772
- 31 + 47741 = 47772
- 59 + 47713 = 47772
- 61 + 47711 = 47772
- 71 + 47701 = 47772
- 73 + 47699 = 47772
- 113 + 47659 = 47772
- 149 + 47623 = 47772
Showing the first eight; more decompositions exist.
