Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139474, here are decompositions:
- 17 + 139457 = 139474
- 107 + 139367 = 139474
- 113 + 139361 = 139474
- 131 + 139343 = 139474
- 173 + 139301 = 139474
- 233 + 139241 = 139474
- 353 + 139121 = 139474
- 383 + 139091 = 139474
Showing the first eight; more decompositions exist.
