Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138060, here are decompositions:
- 7 + 138053 = 138060
- 19 + 138041 = 138060
- 53 + 138007 = 138060
- 61 + 137999 = 138060
- 67 + 137993 = 138060
- 103 + 137957 = 138060
- 113 + 137947 = 138060
- 127 + 137933 = 138060
Showing the first eight; more decompositions exist.
