Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135520, here are decompositions:
- 23 + 135497 = 135520
- 41 + 135479 = 135520
- 53 + 135467 = 135520
- 59 + 135461 = 135520
- 71 + 135449 = 135520
- 89 + 135431 = 135520
- 131 + 135389 = 135520
- 167 + 135353 = 135520
Showing the first eight; more decompositions exist.
