Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78042, here are decompositions:
- 11 + 78031 = 78042
- 43 + 77999 = 78042
- 59 + 77983 = 78042
- 73 + 77969 = 78042
- 109 + 77933 = 78042
- 113 + 77929 = 78042
- 149 + 77893 = 78042
- 179 + 77863 = 78042
Showing the first eight; more decompositions exist.
