Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147472, here are decompositions:
- 23 + 147449 = 147472
- 53 + 147419 = 147472
- 71 + 147401 = 147472
- 131 + 147341 = 147472
- 173 + 147299 = 147472
- 179 + 147293 = 147472
- 251 + 147221 = 147472
- 263 + 147209 = 147472
Showing the first eight; more decompositions exist.
