Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139358, here are decompositions:
- 19 + 139339 = 139358
- 61 + 139297 = 139358
- 67 + 139291 = 139358
- 157 + 139201 = 139358
- 181 + 139177 = 139358
- 337 + 139021 = 139358
- 421 + 138937 = 139358
- 619 + 138739 = 139358
Showing the first eight; more decompositions exist.
