Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42012, here are decompositions:
- 13 + 41999 = 42012
- 29 + 41983 = 42012
- 31 + 41981 = 42012
- 43 + 41969 = 42012
- 53 + 41959 = 42012
- 59 + 41953 = 42012
- 71 + 41941 = 42012
- 101 + 41911 = 42012
Showing the first eight; more decompositions exist.
