Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 552, here are decompositions:
- 5 + 547 = 552
- 11 + 541 = 552
- 29 + 523 = 552
- 31 + 521 = 552
- 43 + 509 = 552
- 53 + 499 = 552
- 61 + 491 = 552
- 73 + 479 = 552
Showing the first eight; more decompositions exist.
