Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61472, here are decompositions:
- 3 + 61469 = 61472
- 31 + 61441 = 61472
- 109 + 61363 = 61472
- 139 + 61333 = 61472
- 181 + 61291 = 61472
- 211 + 61261 = 61472
- 241 + 61231 = 61472
- 331 + 61141 = 61472
Showing the first eight; more decompositions exist.
