Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136620, here are decompositions:
- 13 + 136607 = 136620
- 17 + 136603 = 136620
- 19 + 136601 = 136620
- 47 + 136573 = 136620
- 61 + 136559 = 136620
- 73 + 136547 = 136620
- 79 + 136541 = 136620
- 83 + 136537 = 136620
Showing the first eight; more decompositions exist.
