Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40648, here are decompositions:
- 11 + 40637 = 40648
- 71 + 40577 = 40648
- 89 + 40559 = 40648
- 149 + 40499 = 40648
- 359 + 40289 = 40648
- 479 + 40169 = 40648
- 521 + 40127 = 40648
- 617 + 40031 = 40648
Showing the first eight; more decompositions exist.
