Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78272, here are decompositions:
- 13 + 78259 = 78272
- 31 + 78241 = 78272
- 43 + 78229 = 78272
- 79 + 78193 = 78272
- 109 + 78163 = 78272
- 151 + 78121 = 78272
- 193 + 78079 = 78272
- 223 + 78049 = 78272
Showing the first eight; more decompositions exist.
