Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 58440, here are decompositions:
- 13 + 58427 = 58440
- 23 + 58417 = 58440
- 29 + 58411 = 58440
- 37 + 58403 = 58440
- 47 + 58393 = 58440
- 61 + 58379 = 58440
- 71 + 58369 = 58440
- 73 + 58367 = 58440
Showing the first eight; more decompositions exist.
