Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42266, here are decompositions:
- 43 + 42223 = 42266
- 73 + 42193 = 42266
- 79 + 42187 = 42266
- 97 + 42169 = 42266
- 109 + 42157 = 42266
- 127 + 42139 = 42266
- 193 + 42073 = 42266
- 223 + 42043 = 42266
Showing the first eight; more decompositions exist.
