Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47912, here are decompositions:
- 31 + 47881 = 47912
- 43 + 47869 = 47912
- 103 + 47809 = 47912
- 199 + 47713 = 47912
- 211 + 47701 = 47912
- 283 + 47629 = 47912
- 313 + 47599 = 47912
- 331 + 47581 = 47912
Showing the first eight; more decompositions exist.
