Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177942, here are decompositions:
- 13 + 177929 = 177942
- 29 + 177913 = 177942
- 53 + 177889 = 177942
- 59 + 177883 = 177942
- 101 + 177841 = 177942
- 103 + 177839 = 177942
- 131 + 177811 = 177942
- 151 + 177791 = 177942
Showing the first eight; more decompositions exist.
