Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473508, here are decompositions:

29 + 31473479 = 31473508
71 + 31473437 = 31473508
149 + 31473359 = 31473508
257 + 31473251 = 31473508
317 + 31473191 = 31473508
347 + 31473161 = 31473508
401 + 31473107 = 31473508
431 + 31473077 = 31473508

Showing the first eight; more decompositions exist.
