Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8072, here are decompositions:
- 3 + 8069 = 8072
- 13 + 8059 = 8072
- 19 + 8053 = 8072
- 61 + 8011 = 8072
- 79 + 7993 = 8072
- 109 + 7963 = 8072
- 139 + 7933 = 8072
- 193 + 7879 = 8072
Showing the first eight; more decompositions exist.
