Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472682, here are decompositions:

13 + 31472669 = 31472682
19 + 31472663 = 31472682
71 + 31472611 = 31472682
181 + 31472501 = 31472682
193 + 31472489 = 31472682
233 + 31472449 = 31472682
331 + 31472351 = 31472682
389 + 31472293 = 31472682

Showing the first eight; more decompositions exist.
