Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2672, here are decompositions:
- 13 + 2659 = 2672
- 79 + 2593 = 2672
- 151 + 2521 = 2672
- 199 + 2473 = 2672
- 283 + 2389 = 2672
- 331 + 2341 = 2672
- 379 + 2293 = 2672
- 421 + 2251 = 2672
Showing the first eight; more decompositions exist.
