Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30078, here are decompositions:
- 7 + 30071 = 30078
- 19 + 30059 = 30078
- 31 + 30047 = 30078
- 67 + 30011 = 30078
- 89 + 29989 = 30078
- 131 + 29947 = 30078
- 151 + 29927 = 30078
- 157 + 29921 = 30078
Showing the first eight; more decompositions exist.
