Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121452, here are decompositions:
- 5 + 121447 = 121452
- 11 + 121441 = 121452
- 13 + 121439 = 121452
- 31 + 121421 = 121452
- 73 + 121379 = 121452
- 83 + 121369 = 121452
- 101 + 121351 = 121452
- 103 + 121349 = 121452
Showing the first eight; more decompositions exist.
