Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80580, here are decompositions:
- 13 + 80567 = 80580
- 23 + 80557 = 80580
- 43 + 80537 = 80580
- 53 + 80527 = 80580
- 67 + 80513 = 80580
- 89 + 80491 = 80580
- 107 + 80473 = 80580
- 109 + 80471 = 80580
Showing the first eight; more decompositions exist.
