Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495438, here are decompositions:
- 5 + 495433 = 495438
- 17 + 495421 = 495438
- 37 + 495401 = 495438
- 61 + 495377 = 495438
- 67 + 495371 = 495438
- 79 + 495359 = 495438
- 101 + 495337 = 495438
- 131 + 495307 = 495438
Showing the first eight; more decompositions exist.
