Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66042, here are decompositions:
- 5 + 66037 = 66042
- 13 + 66029 = 66042
- 59 + 65983 = 66042
- 61 + 65981 = 66042
- 79 + 65963 = 66042
- 113 + 65929 = 66042
- 191 + 65851 = 66042
- 199 + 65843 = 66042
Showing the first eight; more decompositions exist.
