Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489046, here are decompositions:

3 + 31489043 = 31489046
19 + 31489027 = 31489046
37 + 31489009 = 31489046
67 + 31488979 = 31489046
139 + 31488907 = 31489046
313 + 31488733 = 31489046
499 + 31488547 = 31489046
577 + 31488469 = 31489046

Showing the first eight; more decompositions exist.
