Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78002, here are decompositions:
- 3 + 77999 = 78002
- 19 + 77983 = 78002
- 73 + 77929 = 78002
- 103 + 77899 = 78002
- 109 + 77893 = 78002
- 139 + 77863 = 78002
- 163 + 77839 = 78002
- 229 + 77773 = 78002
Showing the first eight; more decompositions exist.
