Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43578, here are decompositions:
- 5 + 43573 = 43578
- 37 + 43541 = 43578
- 61 + 43517 = 43578
- 79 + 43499 = 43578
- 97 + 43481 = 43578
- 127 + 43451 = 43578
- 137 + 43441 = 43578
- 151 + 43427 = 43578
Showing the first eight; more decompositions exist.
