Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548038, here are decompositions:

7 + 31548031 = 31548038
31 + 31548007 = 31548038
79 + 31547959 = 31548038
199 + 31547839 = 31548038
307 + 31547731 = 31548038
331 + 31547707 = 31548038
337 + 31547701 = 31548038
367 + 31547671 = 31548038

Showing the first eight; more decompositions exist.
