Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43742, here are decompositions:
- 31 + 43711 = 43742
- 73 + 43669 = 43742
- 109 + 43633 = 43742
- 151 + 43591 = 43742
- 163 + 43579 = 43742
- 199 + 43543 = 43742
- 331 + 43411 = 43742
- 421 + 43321 = 43742
Showing the first eight; more decompositions exist.
