Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30082, here are decompositions:
- 11 + 30071 = 30082
- 23 + 30059 = 30082
- 53 + 30029 = 30082
- 71 + 30011 = 30082
- 263 + 29819 = 30082
- 293 + 29789 = 30082
- 359 + 29723 = 30082
- 419 + 29663 = 30082
Showing the first eight; more decompositions exist.
