Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85272, here are decompositions:
- 13 + 85259 = 85272
- 29 + 85243 = 85272
- 43 + 85229 = 85272
- 59 + 85213 = 85272
- 71 + 85201 = 85272
- 73 + 85199 = 85272
- 79 + 85193 = 85272
- 113 + 85159 = 85272
Showing the first eight; more decompositions exist.
