Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473844, here are decompositions:

5 + 31473839 = 31473844
137 + 31473707 = 31473844
251 + 31473593 = 31473844
263 + 31473581 = 31473844
431 + 31473413 = 31473844
593 + 31473251 = 31473844
641 + 31473203 = 31473844
653 + 31473191 = 31473844

Showing the first eight; more decompositions exist.
