Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473288, here are decompositions:
- 5 + 31473283 = 31473288
- 37 + 31473251 = 31473288
- 47 + 31473241 = 31473288
- 71 + 31473217 = 31473288
- 79 + 31473209 = 31473288
- 97 + 31473191 = 31473288
- 101 + 31473187 = 31473288
- 127 + 31473161 = 31473288
Showing the first eight; more decompositions exist.
