Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504574, here are decompositions:

7 + 31504567 = 31504574
223 + 31504351 = 31504574
271 + 31504303 = 31504574
373 + 31504201 = 31504574
487 + 31504087 = 31504574
523 + 31504051 = 31504574
601 + 31503973 = 31504574
613 + 31503961 = 31504574

Showing the first eight; more decompositions exist.
