Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473178, here are decompositions:

5 + 31473173 = 31473178
17 + 31473161 = 31473178
71 + 31473107 = 31473178
101 + 31473077 = 31473178
137 + 31473041 = 31473178
251 + 31472927 = 31473178
311 + 31472867 = 31473178
479 + 31472699 = 31473178

Showing the first eight; more decompositions exist.
