Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10538, here are decompositions:
- 7 + 10531 = 10538
- 37 + 10501 = 10538
- 61 + 10477 = 10538
- 79 + 10459 = 10538
- 109 + 10429 = 10538
- 139 + 10399 = 10538
- 181 + 10357 = 10538
- 271 + 10267 = 10538
Showing the first eight; more decompositions exist.
