Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472404, here are decompositions:

53 + 31472351 = 31472404
113 + 31472291 = 31472404
251 + 31472153 = 31472404
281 + 31472123 = 31472404
401 + 31472003 = 31472404
503 + 31471901 = 31472404
521 + 31471883 = 31472404
617 + 31471787 = 31472404

Showing the first eight; more decompositions exist.
