Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563004, here are decompositions:

3 + 31563001 = 31563004
17 + 31562987 = 31563004
23 + 31562981 = 31563004
227 + 31562777 = 31563004
293 + 31562711 = 31563004
383 + 31562621 = 31563004
401 + 31562603 = 31563004
461 + 31562543 = 31563004

Showing the first eight; more decompositions exist.
