Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489352, here are decompositions:

3 + 31489349 = 31489352
73 + 31489279 = 31489352
109 + 31489243 = 31489352
283 + 31489069 = 31489352
373 + 31488979 = 31489352
421 + 31488931 = 31489352
619 + 31488733 = 31489352
733 + 31488619 = 31489352

Showing the first eight; more decompositions exist.
