Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473772, here are decompositions:

173 + 31473599 = 31473772
179 + 31473593 = 31473772
191 + 31473581 = 31473772
293 + 31473479 = 31473772
359 + 31473413 = 31473772
509 + 31473263 = 31473772
521 + 31473251 = 31473772
563 + 31473209 = 31473772

Showing the first eight; more decompositions exist.
