Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139346, here are decompositions:
- 3 + 139343 = 139346
- 7 + 139339 = 139346
- 13 + 139333 = 139346
- 37 + 139309 = 139346
- 43 + 139303 = 139346
- 73 + 139273 = 139346
- 79 + 139267 = 139346
- 223 + 139123 = 139346
Showing the first eight; more decompositions exist.
