Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7908, here are decompositions:
- 7 + 7901 = 7908
- 29 + 7879 = 7908
- 31 + 7877 = 7908
- 41 + 7867 = 7908
- 67 + 7841 = 7908
- 79 + 7829 = 7908
- 149 + 7759 = 7908
- 151 + 7757 = 7908
Showing the first eight; more decompositions exist.
