Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78200, here are decompositions:
- 7 + 78193 = 78200
- 37 + 78163 = 78200
- 43 + 78157 = 78200
- 61 + 78139 = 78200
- 79 + 78121 = 78200
- 151 + 78049 = 78200
- 193 + 78007 = 78200
- 223 + 77977 = 78200
Showing the first eight; more decompositions exist.
