Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051638, here are decompositions:
- 17 + 1051621 = 1051638
- 19 + 1051619 = 1051638
- 31 + 1051607 = 1051638
- 37 + 1051601 = 1051638
- 47 + 1051591 = 1051638
- 67 + 1051571 = 1051638
- 79 + 1051559 = 1051638
- 89 + 1051549 = 1051638
Showing the first eight; more decompositions exist.
