Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40228, here are decompositions:
- 59 + 40169 = 40228
- 101 + 40127 = 40228
- 191 + 40037 = 40228
- 197 + 40031 = 40228
- 239 + 39989 = 40228
- 257 + 39971 = 40228
- 359 + 39869 = 40228
- 389 + 39839 = 40228
Showing the first eight; more decompositions exist.
