Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627802, here are decompositions:

163 + 31627639 = 31627802
229 + 31627573 = 31627802
499 + 31627303 = 31627802
541 + 31627261 = 31627802
601 + 31627201 = 31627802
733 + 31627069 = 31627802
751 + 31627051 = 31627802
769 + 31627033 = 31627802

Showing the first eight; more decompositions exist.
