Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43472, here are decompositions:
- 31 + 43441 = 43472
- 61 + 43411 = 43472
- 73 + 43399 = 43472
- 151 + 43321 = 43472
- 181 + 43291 = 43472
- 211 + 43261 = 43472
- 271 + 43201 = 43472
- 283 + 43189 = 43472
Showing the first eight; more decompositions exist.
