Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472482, here are decompositions:

3 + 31472479 = 31472482
131 + 31472351 = 31472482
191 + 31472291 = 31472482
281 + 31472201 = 31472482
359 + 31472123 = 31472482
479 + 31472003 = 31472482
491 + 31471991 = 31472482
599 + 31471883 = 31472482

Showing the first eight; more decompositions exist.
