Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135478, here are decompositions:
- 11 + 135467 = 135478
- 17 + 135461 = 135478
- 29 + 135449 = 135478
- 47 + 135431 = 135478
- 89 + 135389 = 135478
- 131 + 135347 = 135478
- 149 + 135329 = 135478
- 197 + 135281 = 135478
Showing the first eight; more decompositions exist.
