Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2444, here are decompositions:
- 3 + 2441 = 2444
- 7 + 2437 = 2444
- 61 + 2383 = 2444
- 67 + 2377 = 2444
- 73 + 2371 = 2444
- 97 + 2347 = 2444
- 103 + 2341 = 2444
- 151 + 2293 = 2444
Showing the first eight; more decompositions exist.
