Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562848, here are decompositions:

47 + 31562801 = 31562848
71 + 31562777 = 31562848
137 + 31562711 = 31562848
227 + 31562621 = 31562848
281 + 31562567 = 31562848
347 + 31562501 = 31562848
419 + 31562429 = 31562848
491 + 31562357 = 31562848

Showing the first eight; more decompositions exist.
