Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45478, here are decompositions:
- 89 + 45389 = 45478
- 101 + 45377 = 45478
- 137 + 45341 = 45478
- 149 + 45329 = 45478
- 197 + 45281 = 45478
- 281 + 45197 = 45478
- 317 + 45161 = 45478
- 347 + 45131 = 45478
Showing the first eight; more decompositions exist.
