Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42254, here are decompositions:
- 31 + 42223 = 42254
- 61 + 42193 = 42254
- 67 + 42187 = 42254
- 73 + 42181 = 42254
- 97 + 42157 = 42254
- 181 + 42073 = 42254
- 193 + 42061 = 42254
- 211 + 42043 = 42254
Showing the first eight; more decompositions exist.
