Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43648, here are decompositions:
- 41 + 43607 = 43648
- 71 + 43577 = 43648
- 107 + 43541 = 43648
- 131 + 43517 = 43648
- 149 + 43499 = 43648
- 167 + 43481 = 43648
- 191 + 43457 = 43648
- 197 + 43451 = 43648
Showing the first eight; more decompositions exist.
