Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625884, here are decompositions:

41 + 31625843 = 31625884
107 + 31625777 = 31625884
131 + 31625753 = 31625884
233 + 31625651 = 31625884
281 + 31625603 = 31625884
317 + 31625567 = 31625884
347 + 31625537 = 31625884
431 + 31625453 = 31625884

Showing the first eight; more decompositions exist.
