Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69490, here are decompositions:
- 17 + 69473 = 69490
- 23 + 69467 = 69490
- 59 + 69431 = 69490
- 89 + 69401 = 69490
- 101 + 69389 = 69490
- 107 + 69383 = 69490
- 149 + 69341 = 69490
- 173 + 69317 = 69490
Showing the first eight; more decompositions exist.
