Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177278, here are decompositions:
- 61 + 177217 = 177278
- 67 + 177211 = 177278
- 151 + 177127 = 177278
- 271 + 177007 = 177278
- 379 + 176899 = 177278
- 421 + 176857 = 177278
- 487 + 176791 = 177278
- 499 + 176779 = 177278
Showing the first eight; more decompositions exist.
