Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648940, here are decompositions:
- 11 + 8648929 = 8648940
- 17 + 8648923 = 8648940
- 19 + 8648921 = 8648940
- 59 + 8648881 = 8648940
- 61 + 8648879 = 8648940
- 73 + 8648867 = 8648940
- 101 + 8648839 = 8648940
- 103 + 8648837 = 8648940
Showing the first eight; more decompositions exist.
