Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175478, here are decompositions:
- 31 + 175447 = 175478
- 67 + 175411 = 175478
- 151 + 175327 = 175478
- 211 + 175267 = 175478
- 337 + 175141 = 175478
- 349 + 175129 = 175478
- 397 + 175081 = 175478
- 409 + 175069 = 175478
Showing the first eight; more decompositions exist.
