Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144394, here are decompositions:
- 11 + 144383 = 144394
- 53 + 144341 = 144394
- 71 + 144323 = 144394
- 83 + 144311 = 144394
- 191 + 144203 = 144394
- 227 + 144167 = 144394
- 233 + 144161 = 144394
- 521 + 143873 = 144394
Showing the first eight; more decompositions exist.
