Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482712, here are decompositions:

3 + 31482709 = 31482712
5 + 31482707 = 31482712
29 + 31482683 = 31482712
71 + 31482641 = 31482712
113 + 31482599 = 31482712
311 + 31482401 = 31482712
419 + 31482293 = 31482712
431 + 31482281 = 31482712

Showing the first eight; more decompositions exist.
