Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38100, here are decompositions:
- 17 + 38083 = 38100
- 31 + 38069 = 38100
- 47 + 38053 = 38100
- 53 + 38047 = 38100
- 61 + 38039 = 38100
- 89 + 38011 = 38100
- 103 + 37997 = 38100
- 107 + 37993 = 38100
Showing the first eight; more decompositions exist.
