Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473644, here are decompositions:

61 + 31473583 = 31473644
157 + 31473487 = 31473644
313 + 31473331 = 31473644
331 + 31473313 = 31473644
457 + 31473187 = 31473644
577 + 31473067 = 31473644
607 + 31473037 = 31473644
613 + 31473031 = 31473644

Showing the first eight; more decompositions exist.
