Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144338, here are decompositions:
- 31 + 144307 = 144338
- 67 + 144271 = 144338
- 79 + 144259 = 144338
- 97 + 144241 = 144338
- 199 + 144139 = 144338
- 277 + 144061 = 144338
- 307 + 144031 = 144338
- 367 + 143971 = 144338
Showing the first eight; more decompositions exist.
