Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30556, here are decompositions:
- 3 + 30553 = 30556
- 17 + 30539 = 30556
- 47 + 30509 = 30556
- 59 + 30497 = 30556
- 89 + 30467 = 30556
- 107 + 30449 = 30556
- 167 + 30389 = 30556
- 233 + 30323 = 30556
Showing the first eight; more decompositions exist.
