Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85580, here are decompositions:
- 3 + 85577 = 85580
- 31 + 85549 = 85580
- 67 + 85513 = 85580
- 127 + 85453 = 85580
- 151 + 85429 = 85580
- 199 + 85381 = 85580
- 211 + 85369 = 85580
- 277 + 85303 = 85580
Showing the first eight; more decompositions exist.
