Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019742, here are decompositions:
- 11 + 1019731 = 1019742
- 13 + 1019729 = 1019742
- 19 + 1019723 = 1019742
- 29 + 1019713 = 1019742
- 41 + 1019701 = 1019742
- 43 + 1019699 = 1019742
- 79 + 1019663 = 1019742
- 103 + 1019639 = 1019742
Showing the first eight; more decompositions exist.
