Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029438, here are decompositions:
- 5 + 1029433 = 1029438
- 29 + 1029409 = 1029438
- 31 + 1029407 = 1029438
- 79 + 1029359 = 1029438
- 89 + 1029349 = 1029438
- 97 + 1029341 = 1029438
- 101 + 1029337 = 1029438
- 107 + 1029331 = 1029438
Showing the first eight; more decompositions exist.
