Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177844, here are decompositions:
- 3 + 177841 = 177844
- 5 + 177839 = 177844
- 47 + 177797 = 177844
- 53 + 177791 = 177844
- 83 + 177761 = 177844
- 101 + 177743 = 177844
- 167 + 177677 = 177844
- 197 + 177647 = 177844
Showing the first eight; more decompositions exist.
