Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472002, here are decompositions:

11 + 31471991 = 31472002
101 + 31471901 = 31472002
179 + 31471823 = 31472002
239 + 31471763 = 31472002
479 + 31471523 = 31472002
491 + 31471511 = 31472002
521 + 31471481 = 31472002
563 + 31471439 = 31472002

Showing the first eight; more decompositions exist.
