Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138082, here are decompositions:
- 3 + 138079 = 138082
- 5 + 138077 = 138082
- 11 + 138071 = 138082
- 23 + 138059 = 138082
- 29 + 138053 = 138082
- 41 + 138041 = 138082
- 83 + 137999 = 138082
- 89 + 137993 = 138082
Showing the first eight; more decompositions exist.
