Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105478, here are decompositions:
- 11 + 105467 = 105478
- 29 + 105449 = 105478
- 41 + 105437 = 105478
- 71 + 105407 = 105478
- 89 + 105389 = 105478
- 137 + 105341 = 105478
- 227 + 105251 = 105478
- 239 + 105239 = 105478
Showing the first eight; more decompositions exist.
