Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1472, here are decompositions:
- 13 + 1459 = 1472
- 19 + 1453 = 1472
- 43 + 1429 = 1472
- 73 + 1399 = 1472
- 151 + 1321 = 1472
- 181 + 1291 = 1472
- 193 + 1279 = 1472
- 223 + 1249 = 1472
Showing the first eight; more decompositions exist.
