Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177802, here are decompositions:
- 5 + 177797 = 177802
- 11 + 177791 = 177802
- 41 + 177761 = 177802
- 59 + 177743 = 177802
- 179 + 177623 = 177802
- 263 + 177539 = 177802
- 269 + 177533 = 177802
- 419 + 177383 = 177802
Showing the first eight; more decompositions exist.
