Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2546, here are decompositions:
- 3 + 2543 = 2546
- 7 + 2539 = 2546
- 43 + 2503 = 2546
- 73 + 2473 = 2546
- 79 + 2467 = 2546
- 109 + 2437 = 2546
- 157 + 2389 = 2546
- 163 + 2383 = 2546
Showing the first eight; more decompositions exist.
