Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61786, here are decompositions:
- 5 + 61781 = 61786
- 29 + 61757 = 61786
- 83 + 61703 = 61786
- 113 + 61673 = 61786
- 149 + 61637 = 61786
- 173 + 61613 = 61786
- 227 + 61559 = 61786
- 233 + 61553 = 61786
Showing the first eight; more decompositions exist.
