Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473602, here are decompositions:

3 + 31473599 = 31473602
19 + 31473583 = 31473602
73 + 31473529 = 31473602
79 + 31473523 = 31473602
271 + 31473331 = 31473602
439 + 31473163 = 31473602
541 + 31473061 = 31473602
571 + 31473031 = 31473602

Showing the first eight; more decompositions exist.
