Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7888, here are decompositions:
- 5 + 7883 = 7888
- 11 + 7877 = 7888
- 47 + 7841 = 7888
- 59 + 7829 = 7888
- 71 + 7817 = 7888
- 131 + 7757 = 7888
- 197 + 7691 = 7888
- 239 + 7649 = 7888
Showing the first eight; more decompositions exist.
