Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7580, here are decompositions:
- 3 + 7577 = 7580
- 7 + 7573 = 7580
- 19 + 7561 = 7580
- 31 + 7549 = 7580
- 43 + 7537 = 7580
- 73 + 7507 = 7580
- 103 + 7477 = 7580
- 163 + 7417 = 7580
Showing the first eight; more decompositions exist.
