Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164450, here are decompositions:
- 3 + 164447 = 164450
- 7 + 164443 = 164450
- 19 + 164431 = 164450
- 31 + 164419 = 164450
- 37 + 164413 = 164450
- 73 + 164377 = 164450
- 79 + 164371 = 164450
- 109 + 164341 = 164450
Showing the first eight; more decompositions exist.
