Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28214, here are decompositions:
- 3 + 28211 = 28214
- 13 + 28201 = 28214
- 31 + 28183 = 28214
- 103 + 28111 = 28214
- 127 + 28087 = 28214
- 157 + 28057 = 28214
- 163 + 28051 = 28214
- 271 + 27943 = 28214
Showing the first eight; more decompositions exist.
