Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473776, here are decompositions:

43 + 31473733 = 31473776
73 + 31473703 = 31473776
193 + 31473583 = 31473776
379 + 31473397 = 31473776
463 + 31473313 = 31473776
613 + 31473163 = 31473776
709 + 31473067 = 31473776
739 + 31473037 = 31473776

Showing the first eight; more decompositions exist.
