Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38280, here are decompositions:
- 7 + 38273 = 38280
- 19 + 38261 = 38280
- 41 + 38239 = 38280
- 43 + 38237 = 38280
- 61 + 38219 = 38280
- 79 + 38201 = 38280
- 83 + 38197 = 38280
- 97 + 38183 = 38280
Showing the first eight; more decompositions exist.
