Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177838, here are decompositions:
- 41 + 177797 = 177838
- 47 + 177791 = 177838
- 191 + 177647 = 177838
- 491 + 177347 = 177838
- 569 + 177269 = 177838
- 599 + 177239 = 177838
- 827 + 177011 = 177838
- 887 + 176951 = 177838
Showing the first eight; more decompositions exist.
