Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472522, here are decompositions:

43 + 31472479 = 31472522
73 + 31472449 = 31472522
163 + 31472359 = 31472522
229 + 31472293 = 31472522
283 + 31472239 = 31472522
313 + 31472209 = 31472522
331 + 31472191 = 31472522
373 + 31472149 = 31472522

Showing the first eight; more decompositions exist.
