Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003890, here are decompositions:
- 11 + 1003879 = 1003890
- 71 + 1003819 = 1003890
- 73 + 1003817 = 1003890
- 103 + 1003787 = 1003890
- 127 + 1003763 = 1003890
- 137 + 1003753 = 1003890
- 149 + 1003741 = 1003890
- 157 + 1003733 = 1003890
Showing the first eight; more decompositions exist.
