Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473406, here are decompositions:

47 + 31473359 = 31473406
197 + 31473209 = 31473406
233 + 31473173 = 31473406
443 + 31472963 = 31473406
479 + 31472927 = 31473406
557 + 31472849 = 31473406
593 + 31472813 = 31473406
599 + 31472807 = 31473406

Showing the first eight; more decompositions exist.
