Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40520, here are decompositions:
- 13 + 40507 = 40520
- 37 + 40483 = 40520
- 61 + 40459 = 40520
- 97 + 40423 = 40520
- 163 + 40357 = 40520
- 283 + 40237 = 40520
- 307 + 40213 = 40520
- 331 + 40189 = 40520
Showing the first eight; more decompositions exist.
