Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532422, here are decompositions:

83 + 31532339 = 31532422
281 + 31532141 = 31532422
359 + 31532063 = 31532422
401 + 31532021 = 31532422
419 + 31532003 = 31532422
491 + 31531931 = 31532422
743 + 31531679 = 31532422
773 + 31531649 = 31532422

Showing the first eight; more decompositions exist.
