Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473000, here are decompositions:
- 17 + 31472983 = 31473000
- 37 + 31472963 = 31473000
- 71 + 31472929 = 31473000
- 73 + 31472927 = 31473000
- 109 + 31472891 = 31473000
- 113 + 31472887 = 31473000
- 149 + 31472851 = 31473000
- 151 + 31472849 = 31473000
Showing the first eight; more decompositions exist.
