Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42200, here are decompositions:
- 3 + 42197 = 42200
- 7 + 42193 = 42200
- 13 + 42187 = 42200
- 19 + 42181 = 42200
- 31 + 42169 = 42200
- 43 + 42157 = 42200
- 61 + 42139 = 42200
- 127 + 42073 = 42200
Showing the first eight; more decompositions exist.
