Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7954, here are decompositions:
- 3 + 7951 = 7954
- 5 + 7949 = 7954
- 17 + 7937 = 7954
- 47 + 7907 = 7954
- 53 + 7901 = 7954
- 71 + 7883 = 7954
- 101 + 7853 = 7954
- 113 + 7841 = 7954
Showing the first eight; more decompositions exist.
