Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85428, here are decompositions:
- 17 + 85411 = 85428
- 47 + 85381 = 85428
- 59 + 85369 = 85428
- 67 + 85361 = 85428
- 97 + 85331 = 85428
- 131 + 85297 = 85428
- 181 + 85247 = 85428
- 191 + 85237 = 85428
Showing the first eight; more decompositions exist.
