Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118578, here are decompositions:
- 7 + 118571 = 118578
- 29 + 118549 = 118578
- 107 + 118471 = 118578
- 149 + 118429 = 118578
- 167 + 118411 = 118578
- 179 + 118399 = 118578
- 191 + 118387 = 118578
- 281 + 118297 = 118578
Showing the first eight; more decompositions exist.
