Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473002, here are decompositions:

19 + 31472983 = 31473002
73 + 31472929 = 31473002
151 + 31472851 = 31473002
163 + 31472839 = 31473002
229 + 31472773 = 31473002
523 + 31472479 = 31473002
643 + 31472359 = 31473002
709 + 31472293 = 31473002

Showing the first eight; more decompositions exist.
