Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627860, here are decompositions:

59 + 31627801 = 31627860
67 + 31627793 = 31627860
97 + 31627763 = 31627860
107 + 31627753 = 31627860
109 + 31627751 = 31627860
139 + 31627721 = 31627860
211 + 31627649 = 31627860
233 + 31627627 = 31627860

Showing the first eight; more decompositions exist.
