Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473488, here are decompositions:

31 + 31473457 = 31473488
157 + 31473331 = 31473488
271 + 31473217 = 31473488
337 + 31473151 = 31473488
379 + 31473109 = 31473488
421 + 31473067 = 31473488
457 + 31473031 = 31473488
601 + 31472887 = 31473488

Showing the first eight; more decompositions exist.
