Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38380, here are decompositions:
- 3 + 38377 = 38380
- 29 + 38351 = 38380
- 47 + 38333 = 38380
- 53 + 38327 = 38380
- 59 + 38321 = 38380
- 107 + 38273 = 38380
- 149 + 38231 = 38380
- 179 + 38201 = 38380
Showing the first eight; more decompositions exist.
