Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135572, here are decompositions:
- 13 + 135559 = 135572
- 61 + 135511 = 135572
- 103 + 135469 = 135572
- 109 + 135463 = 135572
- 139 + 135433 = 135572
- 163 + 135409 = 135572
- 181 + 135391 = 135572
- 223 + 135349 = 135572
Showing the first eight; more decompositions exist.
