Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488944, here are decompositions:

13 + 31488931 = 31488944
37 + 31488907 = 31488944
211 + 31488733 = 31488944
313 + 31488631 = 31488944
397 + 31488547 = 31488944
463 + 31488481 = 31488944
673 + 31488271 = 31488944
733 + 31488211 = 31488944

Showing the first eight; more decompositions exist.
