Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49580, here are decompositions:
- 31 + 49549 = 49580
- 43 + 49537 = 49580
- 103 + 49477 = 49580
- 151 + 49429 = 49580
- 163 + 49417 = 49580
- 211 + 49369 = 49580
- 241 + 49339 = 49580
- 283 + 49297 = 49580
Showing the first eight; more decompositions exist.
