Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78620, here are decompositions:
- 13 + 78607 = 78620
- 37 + 78583 = 78620
- 43 + 78577 = 78620
- 67 + 78553 = 78620
- 79 + 78541 = 78620
- 103 + 78517 = 78620
- 109 + 78511 = 78620
- 181 + 78439 = 78620
Showing the first eight; more decompositions exist.
