Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7826, here are decompositions:
- 3 + 7823 = 7826
- 37 + 7789 = 7826
- 67 + 7759 = 7826
- 73 + 7753 = 7826
- 103 + 7723 = 7826
- 109 + 7717 = 7826
- 127 + 7699 = 7826
- 139 + 7687 = 7826
Showing the first eight; more decompositions exist.
