Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78284, here are decompositions:
- 7 + 78277 = 78284
- 43 + 78241 = 78284
- 127 + 78157 = 78284
- 163 + 78121 = 78284
- 277 + 78007 = 78284
- 307 + 77977 = 78284
- 421 + 77863 = 78284
- 487 + 77797 = 78284
Showing the first eight; more decompositions exist.
