Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551452, here are decompositions:

43 + 31551409 = 31551452
103 + 31551349 = 31551452
193 + 31551259 = 31551452
313 + 31551139 = 31551452
433 + 31551019 = 31551452
601 + 31550851 = 31551452
619 + 31550833 = 31551452
661 + 31550791 = 31551452

Showing the first eight; more decompositions exist.
