Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534556, here are decompositions:
- 3 + 31534553 = 31534556
- 13 + 31534543 = 31534556
- 73 + 31534483 = 31534556
- 127 + 31534429 = 31534556
- 223 + 31534333 = 31534556
- 373 + 31534183 = 31534556
- 439 + 31534117 = 31534556
- 499 + 31534057 = 31534556
Showing the first eight; more decompositions exist.
