Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472338, here are decompositions:

47 + 31472291 = 31472338
137 + 31472201 = 31472338
179 + 31472159 = 31472338
269 + 31472069 = 31472338
347 + 31471991 = 31472338
431 + 31471907 = 31472338
641 + 31471697 = 31472338
701 + 31471637 = 31472338

Showing the first eight; more decompositions exist.
