Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79580, here are decompositions:
- 19 + 79561 = 79580
- 31 + 79549 = 79580
- 43 + 79537 = 79580
- 157 + 79423 = 79580
- 181 + 79399 = 79580
- 223 + 79357 = 79580
- 271 + 79309 = 79580
- 307 + 79273 = 79580
Showing the first eight; more decompositions exist.
