Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473326, here are decompositions:

13 + 31473313 = 31473326
43 + 31473283 = 31473326
109 + 31473217 = 31473326
139 + 31473187 = 31473326
163 + 31473163 = 31473326
397 + 31472929 = 31473326
439 + 31472887 = 31473326
487 + 31472839 = 31473326

Showing the first eight; more decompositions exist.
