Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4278, here are decompositions:
- 5 + 4273 = 4278
- 7 + 4271 = 4278
- 17 + 4261 = 4278
- 19 + 4259 = 4278
- 37 + 4241 = 4278
- 47 + 4231 = 4278
- 59 + 4219 = 4278
- 61 + 4217 = 4278
Showing the first eight; more decompositions exist.
