Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977940, here are decompositions:
- 13 + 977927 = 977940
- 17 + 977923 = 977940
- 43 + 977897 = 977940
- 59 + 977881 = 977940
- 79 + 977861 = 977940
- 109 + 977831 = 977940
- 127 + 977813 = 977940
- 137 + 977803 = 977940
Showing the first eight; more decompositions exist.
