Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562038, here are decompositions:

5 + 31562033 = 31562038
29 + 31562009 = 31562038
71 + 31561967 = 31562038
191 + 31561847 = 31562038
227 + 31561811 = 31562038
257 + 31561781 = 31562038
461 + 31561577 = 31562038
491 + 31561547 = 31562038

Showing the first eight; more decompositions exist.
