Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177388, here are decompositions:
- 5 + 177383 = 177388
- 41 + 177347 = 177388
- 131 + 177257 = 177388
- 149 + 177239 = 177388
- 179 + 177209 = 177388
- 257 + 177131 = 177388
- 461 + 176927 = 177388
- 467 + 176921 = 177388
Showing the first eight; more decompositions exist.
