Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139202, here are decompositions:
- 3 + 139199 = 139202
- 79 + 139123 = 139202
- 181 + 139021 = 139202
- 313 + 138889 = 139202
- 373 + 138829 = 139202
- 409 + 138793 = 139202
- 439 + 138763 = 139202
- 463 + 138739 = 139202
Showing the first eight; more decompositions exist.
