Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473328, here are decompositions:

137 + 31473191 = 31473328
167 + 31473161 = 31473328
251 + 31473077 = 31473328
401 + 31472927 = 31473328
449 + 31472879 = 31473328
461 + 31472867 = 31473328
479 + 31472849 = 31473328
521 + 31472807 = 31473328

Showing the first eight; more decompositions exist.
