Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485444, here are decompositions:

13 + 31485431 = 31485444
17 + 31485427 = 31485444
37 + 31485407 = 31485444
43 + 31485401 = 31485444
47 + 31485397 = 31485444
61 + 31485383 = 31485444
103 + 31485341 = 31485444
131 + 31485313 = 31485444

Showing the first eight; more decompositions exist.
