Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147448, here are decompositions:
- 29 + 147419 = 147448
- 47 + 147401 = 147448
- 71 + 147377 = 147448
- 101 + 147347 = 147448
- 107 + 147341 = 147448
- 137 + 147311 = 147448
- 149 + 147299 = 147448
- 227 + 147221 = 147448
Showing the first eight; more decompositions exist.
