Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47722, here are decompositions:
- 5 + 47717 = 47722
- 11 + 47711 = 47722
- 23 + 47699 = 47722
- 41 + 47681 = 47722
- 83 + 47639 = 47722
- 113 + 47609 = 47722
- 131 + 47591 = 47722
- 179 + 47543 = 47722
Showing the first eight; more decompositions exist.
