Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163380, here are decompositions:
- 13 + 163367 = 163380
- 17 + 163363 = 163380
- 29 + 163351 = 163380
- 43 + 163337 = 163380
- 53 + 163327 = 163380
- 59 + 163321 = 163380
- 71 + 163309 = 163380
- 73 + 163307 = 163380
Showing the first eight; more decompositions exist.
