Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473688, here are decompositions:

89 + 31473599 = 31473688
107 + 31473581 = 31473688
251 + 31473437 = 31473688
479 + 31473209 = 31473688
647 + 31473041 = 31473688
761 + 31472927 = 31473688
797 + 31472891 = 31473688
809 + 31472879 = 31473688

Showing the first eight; more decompositions exist.
