Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26778, here are decompositions:
- 19 + 26759 = 26778
- 41 + 26737 = 26778
- 47 + 26731 = 26778
- 61 + 26717 = 26778
- 67 + 26711 = 26778
- 79 + 26699 = 26778
- 97 + 26681 = 26778
- 109 + 26669 = 26778
Showing the first eight; more decompositions exist.
