Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42276, here are decompositions:
- 19 + 42257 = 42276
- 37 + 42239 = 42276
- 53 + 42223 = 42276
- 67 + 42209 = 42276
- 79 + 42197 = 42276
- 83 + 42193 = 42276
- 89 + 42187 = 42276
- 97 + 42179 = 42276
Showing the first eight; more decompositions exist.
