Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183438, here are decompositions:
- 41 + 183397 = 183438
- 61 + 183377 = 183438
- 89 + 183349 = 183438
- 109 + 183329 = 183438
- 131 + 183307 = 183438
- 137 + 183301 = 183438
- 139 + 183299 = 183438
- 149 + 183289 = 183438
Showing the first eight; more decompositions exist.
