Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78570, here are decompositions:
- 17 + 78553 = 78570
- 29 + 78541 = 78570
- 31 + 78539 = 78570
- 53 + 78517 = 78570
- 59 + 78511 = 78570
- 61 + 78509 = 78570
- 73 + 78497 = 78570
- 83 + 78487 = 78570
Showing the first eight; more decompositions exist.
