Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28226, here are decompositions:
- 7 + 28219 = 28226
- 43 + 28183 = 28226
- 103 + 28123 = 28226
- 127 + 28099 = 28226
- 139 + 28087 = 28226
- 157 + 28069 = 28226
- 199 + 28027 = 28226
- 229 + 27997 = 28226
Showing the first eight; more decompositions exist.
