Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472548, here are decompositions:

11 + 31472537 = 31472548
47 + 31472501 = 31472548
59 + 31472489 = 31472548
197 + 31472351 = 31472548
257 + 31472291 = 31472548
347 + 31472201 = 31472548
389 + 31472159 = 31472548
479 + 31472069 = 31472548

Showing the first eight; more decompositions exist.
