Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78152, here are decompositions:
- 13 + 78139 = 78152
- 31 + 78121 = 78152
- 73 + 78079 = 78152
- 103 + 78049 = 78152
- 223 + 77929 = 78152
- 313 + 77839 = 78152
- 379 + 77773 = 78152
- 409 + 77743 = 78152
Showing the first eight; more decompositions exist.
