Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473170, here are decompositions:

7 + 31473163 = 31473170
19 + 31473151 = 31473170
61 + 31473109 = 31473170
103 + 31473067 = 31473170
109 + 31473061 = 31473170
139 + 31473031 = 31473170
241 + 31472929 = 31473170
283 + 31472887 = 31473170

Showing the first eight; more decompositions exist.
