Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3380, here are decompositions:
- 7 + 3373 = 3380
- 19 + 3361 = 3380
- 37 + 3343 = 3380
- 61 + 3319 = 3380
- 67 + 3313 = 3380
- 73 + 3307 = 3380
- 79 + 3301 = 3380
- 109 + 3271 = 3380
Showing the first eight; more decompositions exist.
