Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147858, here are decompositions:
- 5 + 147853 = 147858
- 31 + 147827 = 147858
- 47 + 147811 = 147858
- 59 + 147799 = 147858
- 71 + 147787 = 147858
- 79 + 147779 = 147858
- 89 + 147769 = 147858
- 97 + 147761 = 147858
Showing the first eight; more decompositions exist.
