Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473294, here are decompositions:
- 3 + 2147473291 = 2147473294
- 11 + 2147473283 = 2147473294
- 53 + 2147473241 = 2147473294
- 107 + 2147473187 = 2147473294
- 167 + 2147473127 = 2147473294
- 173 + 2147473121 = 2147473294
- 233 + 2147473061 = 2147473294
- 401 + 2147472893 = 2147473294
Showing the first eight; more decompositions exist.
