Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147572, here are decompositions:
- 31 + 147541 = 147572
- 163 + 147409 = 147572
- 181 + 147391 = 147572
- 241 + 147331 = 147572
- 283 + 147289 = 147572
- 409 + 147163 = 147572
- 421 + 147151 = 147572
- 433 + 147139 = 147572
Showing the first eight; more decompositions exist.
