Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68428, here are decompositions:
- 29 + 68399 = 68428
- 149 + 68279 = 68428
- 167 + 68261 = 68428
- 257 + 68171 = 68428
- 281 + 68147 = 68428
- 317 + 68111 = 68428
- 449 + 67979 = 68428
- 461 + 67967 = 68428
Showing the first eight; more decompositions exist.
