Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177580, here are decompositions:
- 41 + 177539 = 177580
- 47 + 177533 = 177580
- 107 + 177473 = 177580
- 113 + 177467 = 177580
- 149 + 177431 = 177580
- 197 + 177383 = 177580
- 233 + 177347 = 177580
- 257 + 177323 = 177580
Showing the first eight; more decompositions exist.
