Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136646, here are decompositions:
- 43 + 136603 = 136646
- 73 + 136573 = 136646
- 109 + 136537 = 136646
- 127 + 136519 = 136646
- 163 + 136483 = 136646
- 193 + 136453 = 136646
- 199 + 136447 = 136646
- 229 + 136417 = 136646
Showing the first eight; more decompositions exist.
