Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30072, here are decompositions:
- 13 + 30059 = 30072
- 43 + 30029 = 30072
- 59 + 30013 = 30072
- 61 + 30011 = 30072
- 83 + 29989 = 30072
- 89 + 29983 = 30072
- 113 + 29959 = 30072
- 151 + 29921 = 30072
Showing the first eight; more decompositions exist.
