Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 452, here are decompositions:
- 3 + 449 = 452
- 13 + 439 = 452
- 19 + 433 = 452
- 31 + 421 = 452
- 43 + 409 = 452
- 73 + 379 = 452
- 79 + 373 = 452
- 103 + 349 = 452
Showing the first eight; more decompositions exist.
