Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147908, here are decompositions:
- 97 + 147811 = 147908
- 109 + 147799 = 147908
- 139 + 147769 = 147908
- 181 + 147727 = 147908
- 199 + 147709 = 147908
- 337 + 147571 = 147908
- 367 + 147541 = 147908
- 421 + 147487 = 147908
Showing the first eight; more decompositions exist.
