Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78150, here are decompositions:
- 11 + 78139 = 78150
- 13 + 78137 = 78150
- 29 + 78121 = 78150
- 71 + 78079 = 78150
- 101 + 78049 = 78150
- 109 + 78041 = 78150
- 151 + 77999 = 78150
- 167 + 77983 = 78150
Showing the first eight; more decompositions exist.
