Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28898, here are decompositions:
- 19 + 28879 = 28898
- 31 + 28867 = 28898
- 61 + 28837 = 28898
- 109 + 28789 = 28898
- 127 + 28771 = 28898
- 139 + 28759 = 28898
- 211 + 28687 = 28898
- 229 + 28669 = 28898
Showing the first eight; more decompositions exist.
