Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3438, here are decompositions:
- 5 + 3433 = 3438
- 31 + 3407 = 3438
- 47 + 3391 = 3438
- 67 + 3371 = 3438
- 79 + 3359 = 3438
- 107 + 3331 = 3438
- 109 + 3329 = 3438
- 131 + 3307 = 3438
Showing the first eight; more decompositions exist.
