Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472562, here are decompositions:

61 + 31472501 = 31472562
73 + 31472489 = 31472562
83 + 31472479 = 31472562
113 + 31472449 = 31472562
211 + 31472351 = 31472562
223 + 31472339 = 31472562
269 + 31472293 = 31472562
271 + 31472291 = 31472562

Showing the first eight; more decompositions exist.
