Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69438, here are decompositions:
- 7 + 69431 = 69438
- 11 + 69427 = 69438
- 37 + 69401 = 69438
- 59 + 69379 = 69438
- 67 + 69371 = 69438
- 97 + 69341 = 69438
- 101 + 69337 = 69438
- 179 + 69259 = 69438
Showing the first eight; more decompositions exist.
