Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30492, here are decompositions:
- 23 + 30469 = 30492
- 43 + 30449 = 30492
- 61 + 30431 = 30492
- 89 + 30403 = 30492
- 101 + 30391 = 30492
- 103 + 30389 = 30492
- 151 + 30341 = 30492
- 173 + 30319 = 30492
Showing the first eight; more decompositions exist.
