Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504472, here are decompositions:
- 19 + 31504453 = 31504472
- 271 + 31504201 = 31504472
- 283 + 31504189 = 31504472
- 421 + 31504051 = 31504472
- 499 + 31503973 = 31504472
- 541 + 31503931 = 31504472
- 619 + 31503853 = 31504472
- 631 + 31503841 = 31504472
Showing the first eight; more decompositions exist.
