Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473730, here are decompositions:
- 23 + 31473707 = 31473730
- 131 + 31473599 = 31473730
- 137 + 31473593 = 31473730
- 149 + 31473581 = 31473730
- 251 + 31473479 = 31473730
- 293 + 31473437 = 31473730
- 317 + 31473413 = 31473730
- 467 + 31473263 = 31473730
Showing the first eight; more decompositions exist.
