Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473034, here are decompositions:

3 + 31473031 = 31473034
71 + 31472963 = 31473034
107 + 31472927 = 31473034
167 + 31472867 = 31473034
227 + 31472807 = 31473034
311 + 31472723 = 31473034
401 + 31472633 = 31473034
443 + 31472591 = 31473034

Showing the first eight; more decompositions exist.
