Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618940, here are decompositions:
- 7 + 8618933 = 8618940
- 17 + 8618923 = 8618940
- 23 + 8618917 = 8618940
- 47 + 8618893 = 8618940
- 61 + 8618879 = 8618940
- 73 + 8618867 = 8618940
- 79 + 8618861 = 8618940
- 89 + 8618851 = 8618940
Showing the first eight; more decompositions exist.
