Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473358, here are decompositions:

107 + 31473251 = 31473358
149 + 31473209 = 31473358
167 + 31473191 = 31473358
197 + 31473161 = 31473358
251 + 31473107 = 31473358
281 + 31473077 = 31473358
317 + 31473041 = 31473358
431 + 31472927 = 31473358

Showing the first eight; more decompositions exist.
