Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61780, here are decompositions:
- 23 + 61757 = 61780
- 29 + 61751 = 61780
- 107 + 61673 = 61780
- 113 + 61667 = 61780
- 137 + 61643 = 61780
- 149 + 61631 = 61780
- 167 + 61613 = 61780
- 197 + 61583 = 61780
Showing the first eight; more decompositions exist.
