Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78030, here are decompositions:
- 13 + 78017 = 78030
- 23 + 78007 = 78030
- 31 + 77999 = 78030
- 47 + 77983 = 78030
- 53 + 77977 = 78030
- 61 + 77969 = 78030
- 79 + 77951 = 78030
- 97 + 77933 = 78030
Showing the first eight; more decompositions exist.
