Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027890, here are decompositions:
- 7 + 1027883 = 1027890
- 37 + 1027853 = 1027890
- 103 + 1027787 = 1027890
- 107 + 1027783 = 1027890
- 113 + 1027777 = 1027890
- 131 + 1027759 = 1027890
- 137 + 1027753 = 1027890
- 139 + 1027751 = 1027890
Showing the first eight; more decompositions exist.
