Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482650, here are decompositions:

7 + 31482643 = 31482650
19 + 31482631 = 31482650
37 + 31482613 = 31482650
139 + 31482511 = 31482650
151 + 31482499 = 31482650
211 + 31482439 = 31482650
223 + 31482427 = 31482650
307 + 31482343 = 31482650

Showing the first eight; more decompositions exist.
