Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489532, here are decompositions:

13 + 31489519 = 31489532
43 + 31489489 = 31489532
463 + 31489069 = 31489532
523 + 31489009 = 31489532
541 + 31488991 = 31489532
601 + 31488931 = 31489532
673 + 31488859 = 31489532
733 + 31488799 = 31489532

Showing the first eight; more decompositions exist.
