Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47770, here are decompositions:
- 29 + 47741 = 47770
- 53 + 47717 = 47770
- 59 + 47711 = 47770
- 71 + 47699 = 47770
- 89 + 47681 = 47770
- 113 + 47657 = 47770
- 131 + 47639 = 47770
- 179 + 47591 = 47770
Showing the first eight; more decompositions exist.
