Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2612, here are decompositions:
- 3 + 2609 = 2612
- 19 + 2593 = 2612
- 61 + 2551 = 2612
- 73 + 2539 = 2612
- 109 + 2503 = 2612
- 139 + 2473 = 2612
- 223 + 2389 = 2612
- 229 + 2383 = 2612
Showing the first eight; more decompositions exist.
