Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190138, here are decompositions:
- 17 + 190121 = 190138
- 41 + 190097 = 190138
- 107 + 190031 = 190138
- 149 + 189989 = 190138
- 191 + 189947 = 190138
- 251 + 189887 = 190138
- 257 + 189881 = 190138
- 467 + 189671 = 190138
Showing the first eight; more decompositions exist.
