Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503794, here are decompositions:
- 43 + 31503751 = 31503794
- 61 + 31503733 = 31503794
- 67 + 31503727 = 31503794
- 151 + 31503643 = 31503794
- 163 + 31503631 = 31503794
- 241 + 31503553 = 31503794
- 433 + 31503361 = 31503794
- 457 + 31503337 = 31503794
Showing the first eight; more decompositions exist.
