Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78018, here are decompositions:
- 11 + 78007 = 78018
- 19 + 77999 = 78018
- 41 + 77977 = 78018
- 67 + 77951 = 78018
- 89 + 77929 = 78018
- 151 + 77867 = 78018
- 179 + 77839 = 78018
- 257 + 77761 = 78018
Showing the first eight; more decompositions exist.
