Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4388, here are decompositions:
- 31 + 4357 = 4388
- 61 + 4327 = 4388
- 127 + 4261 = 4388
- 157 + 4231 = 4388
- 211 + 4177 = 4388
- 229 + 4159 = 4388
- 277 + 4111 = 4388
- 331 + 4057 = 4388
Showing the first eight; more decompositions exist.
