Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38438, here are decompositions:
- 7 + 38431 = 38438
- 61 + 38377 = 38438
- 67 + 38371 = 38438
- 109 + 38329 = 38438
- 139 + 38299 = 38438
- 151 + 38287 = 38438
- 157 + 38281 = 38438
- 199 + 38239 = 38438
Showing the first eight; more decompositions exist.
