Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473150, here are decompositions:

41 + 31473109 = 31473150
43 + 31473107 = 31473150
67 + 31473083 = 31473150
73 + 31473077 = 31473150
83 + 31473067 = 31473150
89 + 31473061 = 31473150
109 + 31473041 = 31473150
113 + 31473037 = 31473150

Showing the first eight; more decompositions exist.
