Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488974, here are decompositions:

3 + 31488971 = 31488974
43 + 31488931 = 31488974
67 + 31488907 = 31488974
241 + 31488733 = 31488974
541 + 31488433 = 31488974
883 + 31488091 = 31488974
997 + 31487977 = 31488974
1033 + 31487941 = 31488974

Showing the first eight; more decompositions exist.
