Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472574, here are decompositions:

37 + 31472537 = 31472574
73 + 31472501 = 31472574
137 + 31472437 = 31472574
223 + 31472351 = 31472574
281 + 31472293 = 31472574
283 + 31472291 = 31472574
313 + 31472261 = 31472574
373 + 31472201 = 31472574

Showing the first eight; more decompositions exist.
