Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 554, here are decompositions:
- 7 + 547 = 554
- 13 + 541 = 554
- 31 + 523 = 554
- 67 + 487 = 554
- 97 + 457 = 554
- 157 + 397 = 554
- 181 + 373 = 554
- 223 + 331 = 554
Showing the first eight; more decompositions exist.
