Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78012, here are decompositions:
- 5 + 78007 = 78012
- 13 + 77999 = 78012
- 29 + 77983 = 78012
- 43 + 77969 = 78012
- 61 + 77951 = 78012
- 79 + 77933 = 78012
- 83 + 77929 = 78012
- 113 + 77899 = 78012
Showing the first eight; more decompositions exist.
