Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485734, here are decompositions:

13 + 31485721 = 31485734
73 + 31485661 = 31485734
151 + 31485583 = 31485734
193 + 31485541 = 31485734
307 + 31485427 = 31485734
337 + 31485397 = 31485734
421 + 31485313 = 31485734
433 + 31485301 = 31485734

Showing the first eight; more decompositions exist.
