Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65130, here are decompositions:
- 7 + 65123 = 65130
- 11 + 65119 = 65130
- 19 + 65111 = 65130
- 29 + 65101 = 65130
- 31 + 65099 = 65130
- 41 + 65089 = 65130
- 59 + 65071 = 65130
- 67 + 65063 = 65130
Showing the first eight; more decompositions exist.
