Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473008, here are decompositions:

79 + 31472929 = 31473008
157 + 31472851 = 31473008
181 + 31472827 = 31473008
397 + 31472611 = 31473008
421 + 31472587 = 31473008
571 + 31472437 = 31473008
769 + 31472239 = 31473008
829 + 31472179 = 31473008

Showing the first eight; more decompositions exist.
