Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167544, here are decompositions:
- 7 + 167537 = 167544
- 23 + 167521 = 167544
- 53 + 167491 = 167544
- 61 + 167483 = 167544
- 73 + 167471 = 167544
- 101 + 167443 = 167544
- 103 + 167441 = 167544
- 107 + 167437 = 167544
Showing the first eight; more decompositions exist.
