Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163470, here are decompositions:
- 37 + 163433 = 163470
- 53 + 163417 = 163470
- 59 + 163411 = 163470
- 61 + 163409 = 163470
- 67 + 163403 = 163470
- 103 + 163367 = 163470
- 107 + 163363 = 163470
- 149 + 163321 = 163470
Showing the first eight; more decompositions exist.
