Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177430, here are decompositions:
- 3 + 177427 = 177430
- 47 + 177383 = 177430
- 83 + 177347 = 177430
- 107 + 177323 = 177430
- 173 + 177257 = 177430
- 191 + 177239 = 177430
- 257 + 177173 = 177430
- 263 + 177167 = 177430
Showing the first eight; more decompositions exist.
