Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 544, here are decompositions:
- 3 + 541 = 544
- 23 + 521 = 544
- 41 + 503 = 544
- 53 + 491 = 544
- 83 + 461 = 544
- 101 + 443 = 544
- 113 + 431 = 544
- 191 + 353 = 544
Showing the first eight; more decompositions exist.
