Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30624, here are decompositions:
- 31 + 30593 = 30624
- 47 + 30577 = 30624
- 67 + 30557 = 30624
- 71 + 30553 = 30624
- 107 + 30517 = 30624
- 127 + 30497 = 30624
- 131 + 30493 = 30624
- 157 + 30467 = 30624
Showing the first eight; more decompositions exist.
