Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4290, here are decompositions:
- 7 + 4283 = 4290
- 17 + 4273 = 4290
- 19 + 4271 = 4290
- 29 + 4261 = 4290
- 31 + 4259 = 4290
- 37 + 4253 = 4290
- 47 + 4243 = 4290
- 59 + 4231 = 4290
Showing the first eight; more decompositions exist.
