Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003818, here are decompositions:
- 31 + 1003787 = 1003818
- 47 + 1003771 = 1003818
- 61 + 1003757 = 1003818
- 71 + 1003747 = 1003818
- 89 + 1003729 = 1003818
- 107 + 1003711 = 1003818
- 139 + 1003679 = 1003818
- 191 + 1003627 = 1003818
Showing the first eight; more decompositions exist.
