Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551752, here are decompositions:

19 + 31551733 = 31551752
31 + 31551721 = 31551752
139 + 31551613 = 31551752
433 + 31551319 = 31551752
601 + 31551151 = 31551752
613 + 31551139 = 31551752
733 + 31551019 = 31551752
829 + 31550923 = 31551752

Showing the first eight; more decompositions exist.
