Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30090, here are decompositions:
- 19 + 30071 = 30090
- 31 + 30059 = 30090
- 43 + 30047 = 30090
- 61 + 30029 = 30090
- 79 + 30011 = 30090
- 101 + 29989 = 30090
- 107 + 29983 = 30090
- 131 + 29959 = 30090
Showing the first eight; more decompositions exist.
