Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47280, here are decompositions:
- 11 + 47269 = 47280
- 29 + 47251 = 47280
- 43 + 47237 = 47280
- 59 + 47221 = 47280
- 73 + 47207 = 47280
- 131 + 47149 = 47280
- 137 + 47143 = 47280
- 151 + 47129 = 47280
Showing the first eight; more decompositions exist.
