Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30472, here are decompositions:
- 3 + 30469 = 30472
- 5 + 30467 = 30472
- 23 + 30449 = 30472
- 41 + 30431 = 30472
- 83 + 30389 = 30472
- 131 + 30341 = 30472
- 149 + 30323 = 30472
- 179 + 30293 = 30472
Showing the first eight; more decompositions exist.
