Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47900, here are decompositions:
- 19 + 47881 = 47900
- 31 + 47869 = 47900
- 43 + 47857 = 47900
- 103 + 47797 = 47900
- 109 + 47791 = 47900
- 157 + 47743 = 47900
- 163 + 47737 = 47900
- 199 + 47701 = 47900
Showing the first eight; more decompositions exist.
