Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80012, here are decompositions:
- 13 + 79999 = 80012
- 73 + 79939 = 80012
- 109 + 79903 = 80012
- 139 + 79873 = 80012
- 151 + 79861 = 80012
- 199 + 79813 = 80012
- 211 + 79801 = 80012
- 313 + 79699 = 80012
Showing the first eight; more decompositions exist.
