Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47540, here are decompositions:
- 7 + 47533 = 47540
- 13 + 47527 = 47540
- 19 + 47521 = 47540
- 43 + 47497 = 47540
- 109 + 47431 = 47540
- 151 + 47389 = 47540
- 223 + 47317 = 47540
- 271 + 47269 = 47540
Showing the first eight; more decompositions exist.
