Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28044, here are decompositions:
- 13 + 28031 = 28044
- 17 + 28027 = 28044
- 43 + 28001 = 28044
- 47 + 27997 = 28044
- 61 + 27983 = 28044
- 83 + 27961 = 28044
- 97 + 27947 = 28044
- 101 + 27943 = 28044
Showing the first eight; more decompositions exist.
