Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7926, here are decompositions:
- 7 + 7919 = 7926
- 19 + 7907 = 7926
- 43 + 7883 = 7926
- 47 + 7879 = 7926
- 53 + 7873 = 7926
- 59 + 7867 = 7926
- 73 + 7853 = 7926
- 97 + 7829 = 7926
Showing the first eight; more decompositions exist.
