Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47238, here are decompositions:
- 17 + 47221 = 47238
- 31 + 47207 = 47238
- 89 + 47149 = 47238
- 101 + 47137 = 47238
- 109 + 47129 = 47238
- 127 + 47111 = 47238
- 151 + 47087 = 47238
- 179 + 47059 = 47238
Showing the first eight; more decompositions exist.
