Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489364, here are decompositions:

337 + 31489027 = 31489364
373 + 31488991 = 31489364
433 + 31488931 = 31489364
457 + 31488907 = 31489364
631 + 31488733 = 31489364
733 + 31488631 = 31489364
883 + 31488481 = 31489364
1093 + 31488271 = 31489364

Showing the first eight; more decompositions exist.
