Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472662, here are decompositions:

29 + 31472633 = 31472662
71 + 31472591 = 31472662
173 + 31472489 = 31472662
311 + 31472351 = 31472662
401 + 31472261 = 31472662
461 + 31472201 = 31472662
479 + 31472183 = 31472662
503 + 31472159 = 31472662

Showing the first eight; more decompositions exist.
