Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147638, here are decompositions:
- 31 + 147607 = 147638
- 67 + 147571 = 147638
- 97 + 147541 = 147638
- 151 + 147487 = 147638
- 157 + 147481 = 147638
- 181 + 147457 = 147638
- 229 + 147409 = 147638
- 241 + 147397 = 147638
Showing the first eight; more decompositions exist.
