Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42572, here are decompositions:
- 3 + 42569 = 42572
- 73 + 42499 = 42572
- 109 + 42463 = 42572
- 139 + 42433 = 42572
- 163 + 42409 = 42572
- 181 + 42391 = 42572
- 193 + 42379 = 42572
- 199 + 42373 = 42572
Showing the first eight; more decompositions exist.
