Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47802, here are decompositions:
- 5 + 47797 = 47802
- 11 + 47791 = 47802
- 23 + 47779 = 47802
- 59 + 47743 = 47802
- 61 + 47741 = 47802
- 89 + 47713 = 47802
- 101 + 47701 = 47802
- 103 + 47699 = 47802
Showing the first eight; more decompositions exist.
