Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121576, here are decompositions:
- 5 + 121571 = 121576
- 17 + 121559 = 121576
- 23 + 121553 = 121576
- 29 + 121547 = 121576
- 53 + 121523 = 121576
- 83 + 121493 = 121576
- 89 + 121487 = 121576
- 107 + 121469 = 121576
Showing the first eight; more decompositions exist.
