Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38142, here are decompositions:
- 23 + 38119 = 38142
- 29 + 38113 = 38142
- 59 + 38083 = 38142
- 73 + 38069 = 38142
- 89 + 38053 = 38142
- 103 + 38039 = 38142
- 131 + 38011 = 38142
- 149 + 37993 = 38142
Showing the first eight; more decompositions exist.
