Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43572, here are decompositions:
- 29 + 43543 = 43572
- 31 + 43541 = 43572
- 73 + 43499 = 43572
- 131 + 43441 = 43572
- 173 + 43399 = 43572
- 181 + 43391 = 43572
- 241 + 43331 = 43572
- 251 + 43321 = 43572
Showing the first eight; more decompositions exist.
