Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78148, here are decompositions:
- 11 + 78137 = 78148
- 47 + 78101 = 78148
- 89 + 78059 = 78148
- 107 + 78041 = 78148
- 131 + 78017 = 78148
- 149 + 77999 = 78148
- 179 + 77969 = 78148
- 197 + 77951 = 78148
Showing the first eight; more decompositions exist.
