Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468884, here are decompositions:

23 + 31468861 = 31468884
61 + 31468823 = 31468884
107 + 31468777 = 31468884
127 + 31468757 = 31468884
157 + 31468727 = 31468884
311 + 31468573 = 31468884
313 + 31468571 = 31468884
331 + 31468553 = 31468884

Showing the first eight; more decompositions exist.
