Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76380, here are decompositions:
- 11 + 76369 = 76380
- 13 + 76367 = 76380
- 37 + 76343 = 76380
- 47 + 76333 = 76380
- 97 + 76283 = 76380
- 127 + 76253 = 76380
- 131 + 76249 = 76380
- 137 + 76243 = 76380
Showing the first eight; more decompositions exist.
