Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42078, here are decompositions:
- 5 + 42073 = 42078
- 7 + 42071 = 42078
- 17 + 42061 = 42078
- 59 + 42019 = 42078
- 61 + 42017 = 42078
- 79 + 41999 = 42078
- 97 + 41981 = 42078
- 109 + 41969 = 42078
Showing the first eight; more decompositions exist.
