Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38172, here are decompositions:
- 5 + 38167 = 38172
- 19 + 38153 = 38172
- 23 + 38149 = 38172
- 53 + 38119 = 38172
- 59 + 38113 = 38172
- 89 + 38083 = 38172
- 103 + 38069 = 38172
- 179 + 37993 = 38172
Showing the first eight; more decompositions exist.
