Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473628, here are decompositions:

29 + 31473599 = 31473628
47 + 31473581 = 31473628
149 + 31473479 = 31473628
191 + 31473437 = 31473628
269 + 31473359 = 31473628
419 + 31473209 = 31473628
467 + 31473161 = 31473628
521 + 31473107 = 31473628

Showing the first eight; more decompositions exist.
