Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42980, here are decompositions:
- 13 + 42967 = 42980
- 19 + 42961 = 42980
- 37 + 42943 = 42980
- 43 + 42937 = 42980
- 79 + 42901 = 42980
- 127 + 42853 = 42980
- 139 + 42841 = 42980
- 151 + 42829 = 42980
Showing the first eight; more decompositions exist.
