Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47494, here are decompositions:
- 3 + 47491 = 47494
- 53 + 47441 = 47494
- 107 + 47387 = 47494
- 113 + 47381 = 47494
- 131 + 47363 = 47494
- 191 + 47303 = 47494
- 197 + 47297 = 47494
- 257 + 47237 = 47494
Showing the first eight; more decompositions exist.
