Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78130, here are decompositions:
- 29 + 78101 = 78130
- 71 + 78059 = 78130
- 89 + 78041 = 78130
- 113 + 78017 = 78130
- 131 + 77999 = 78130
- 179 + 77951 = 78130
- 197 + 77933 = 78130
- 263 + 77867 = 78130
Showing the first eight; more decompositions exist.
