Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 48138, here are decompositions:
- 7 + 48131 = 48138
- 17 + 48121 = 48138
- 19 + 48119 = 48138
- 29 + 48109 = 48138
- 47 + 48091 = 48138
- 59 + 48079 = 48138
- 89 + 48049 = 48138
- 109 + 48029 = 48138
Showing the first eight; more decompositions exist.
