Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47688, here are decompositions:
- 7 + 47681 = 47688
- 29 + 47659 = 47688
- 31 + 47657 = 47688
- 59 + 47629 = 47688
- 79 + 47609 = 47688
- 89 + 47599 = 47688
- 97 + 47591 = 47688
- 107 + 47581 = 47688
Showing the first eight; more decompositions exist.
