Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47780, here are decompositions:
- 3 + 47777 = 47780
- 37 + 47743 = 47780
- 43 + 47737 = 47780
- 67 + 47713 = 47780
- 79 + 47701 = 47780
- 127 + 47653 = 47780
- 151 + 47629 = 47780
- 157 + 47623 = 47780
Showing the first eight; more decompositions exist.
