Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532392, here are decompositions:

53 + 31532339 = 31532392
113 + 31532279 = 31532392
131 + 31532261 = 31532392
173 + 31532219 = 31532392
251 + 31532141 = 31532392
389 + 31532003 = 31532392
461 + 31531931 = 31532392
509 + 31531883 = 31532392

Showing the first eight; more decompositions exist.
