Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49138, here are decompositions:
- 17 + 49121 = 49138
- 29 + 49109 = 49138
- 101 + 49037 = 49138
- 107 + 49031 = 49138
- 149 + 48989 = 49138
- 191 + 48947 = 49138
- 269 + 48869 = 49138
- 281 + 48857 = 49138
Showing the first eight; more decompositions exist.
