Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294963440, here are decompositions:
- 11 + 4294963429 = 4294963440
- 13 + 4294963427 = 4294963440
- 71 + 4294963369 = 4294963440
- 107 + 4294963333 = 4294963440
- 127 + 4294963313 = 4294963440
- 149 + 4294963291 = 4294963440
- 269 + 4294963171 = 4294963440
- 347 + 4294963093 = 4294963440
Showing the first eight; more decompositions exist.
