Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28994, here are decompositions:
- 61 + 28933 = 28994
- 67 + 28927 = 28994
- 73 + 28921 = 28994
- 127 + 28867 = 28994
- 151 + 28843 = 28994
- 157 + 28837 = 28994
- 181 + 28813 = 28994
- 223 + 28771 = 28994
Showing the first eight; more decompositions exist.
