Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532428, here are decompositions:

89 + 31532339 = 31532428
149 + 31532279 = 31532428
167 + 31532261 = 31532428
311 + 31532117 = 31532428
461 + 31531967 = 31532428
677 + 31531751 = 31532428
701 + 31531727 = 31532428
761 + 31531667 = 31532428

Showing the first eight; more decompositions exist.
