Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2648, here are decompositions:
- 31 + 2617 = 2648
- 97 + 2551 = 2648
- 109 + 2539 = 2648
- 127 + 2521 = 2648
- 181 + 2467 = 2648
- 211 + 2437 = 2648
- 271 + 2377 = 2648
- 277 + 2371 = 2648
Showing the first eight; more decompositions exist.
