Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47390, here are decompositions:
- 3 + 47387 = 47390
- 37 + 47353 = 47390
- 73 + 47317 = 47390
- 97 + 47293 = 47390
- 103 + 47287 = 47390
- 139 + 47251 = 47390
- 229 + 47161 = 47390
- 241 + 47149 = 47390
Showing the first eight; more decompositions exist.
