Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177232, here are decompositions:
- 23 + 177209 = 177232
- 59 + 177173 = 177232
- 101 + 177131 = 177232
- 131 + 177101 = 177232
- 281 + 176951 = 177232
- 311 + 176921 = 177232
- 383 + 176849 = 177232
- 443 + 176789 = 177232
Showing the first eight; more decompositions exist.
