Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189544, here are decompositions:
- 53 + 189491 = 189544
- 71 + 189473 = 189544
- 107 + 189437 = 189544
- 137 + 189407 = 189544
- 167 + 189377 = 189544
- 191 + 189353 = 189544
- 197 + 189347 = 189544
- 233 + 189311 = 189544
Showing the first eight; more decompositions exist.
