Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472560, here are decompositions:

23 + 31472537 = 31472560
59 + 31472501 = 31472560
71 + 31472489 = 31472560
269 + 31472291 = 31472560
359 + 31472201 = 31472560
401 + 31472159 = 31472560
491 + 31472069 = 31472560
557 + 31472003 = 31472560

Showing the first eight; more decompositions exist.
