Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121588, here are decompositions:
- 11 + 121577 = 121588
- 17 + 121571 = 121588
- 29 + 121559 = 121588
- 41 + 121547 = 121588
- 101 + 121487 = 121588
- 149 + 121439 = 121588
- 167 + 121421 = 121588
- 239 + 121349 = 121588
Showing the first eight; more decompositions exist.
