Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85772, here are decompositions:
- 61 + 85711 = 85772
- 103 + 85669 = 85772
- 151 + 85621 = 85772
- 223 + 85549 = 85772
- 241 + 85531 = 85772
- 409 + 85363 = 85772
- 439 + 85333 = 85772
- 571 + 85201 = 85772
Showing the first eight; more decompositions exist.
