Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947280, here are decompositions:
- 17 + 947263 = 947280
- 41 + 947239 = 947280
- 83 + 947197 = 947280
- 97 + 947183 = 947280
- 109 + 947171 = 947280
- 151 + 947129 = 947280
- 197 + 947083 = 947280
- 283 + 946997 = 947280
Showing the first eight; more decompositions exist.
