Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28974, here are decompositions:
- 13 + 28961 = 28974
- 41 + 28933 = 28974
- 47 + 28927 = 28974
- 53 + 28921 = 28974
- 73 + 28901 = 28974
- 103 + 28871 = 28974
- 107 + 28867 = 28974
- 131 + 28843 = 28974
Showing the first eight; more decompositions exist.
