Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84130, here are decompositions:
- 3 + 84127 = 84130
- 41 + 84089 = 84130
- 71 + 84059 = 84130
- 83 + 84047 = 84130
- 113 + 84017 = 84130
- 191 + 83939 = 84130
- 197 + 83933 = 84130
- 227 + 83903 = 84130
Showing the first eight; more decompositions exist.
