Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472554, here are decompositions:

17 + 31472537 = 31472554
53 + 31472501 = 31472554
263 + 31472291 = 31472554
293 + 31472261 = 31472554
353 + 31472201 = 31472554
401 + 31472153 = 31472554
431 + 31472123 = 31472554
563 + 31471991 = 31472554

Showing the first eight; more decompositions exist.
