Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79940, here are decompositions:
- 37 + 79903 = 79940
- 67 + 79873 = 79940
- 73 + 79867 = 79940
- 79 + 79861 = 79940
- 97 + 79843 = 79940
- 127 + 79813 = 79940
- 139 + 79801 = 79940
- 163 + 79777 = 79940
Showing the first eight; more decompositions exist.
