Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503250, here are decompositions:
- 41 + 31503209 = 31503250
- 47 + 31503203 = 31503250
- 71 + 31503179 = 31503250
- 83 + 31503167 = 31503250
- 131 + 31503119 = 31503250
- 197 + 31503053 = 31503250
- 257 + 31502993 = 31503250
- 353 + 31502897 = 31503250
Showing the first eight; more decompositions exist.
