Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27042, here are decompositions:
- 11 + 27031 = 27042
- 31 + 27011 = 27042
- 61 + 26981 = 27042
- 83 + 26959 = 27042
- 89 + 26953 = 27042
- 139 + 26903 = 27042
- 149 + 26893 = 27042
- 151 + 26891 = 27042
Showing the first eight; more decompositions exist.
