Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143578, here are decompositions:
- 5 + 143573 = 143578
- 11 + 143567 = 143578
- 41 + 143537 = 143578
- 59 + 143519 = 143578
- 89 + 143489 = 143578
- 101 + 143477 = 143578
- 191 + 143387 = 143578
- 317 + 143261 = 143578
Showing the first eight; more decompositions exist.
