Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78612, here are decompositions:
- 5 + 78607 = 78612
- 19 + 78593 = 78612
- 29 + 78583 = 78612
- 41 + 78571 = 78612
- 43 + 78569 = 78612
- 59 + 78553 = 78612
- 71 + 78541 = 78612
- 73 + 78539 = 78612
Showing the first eight; more decompositions exist.
