Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542338, here are decompositions:

109 + 31542229 = 31542338
271 + 31542067 = 31542338
307 + 31542031 = 31542338
337 + 31542001 = 31542338
349 + 31541989 = 31542338
367 + 31541971 = 31542338
439 + 31541899 = 31542338
577 + 31541761 = 31542338

Showing the first eight; more decompositions exist.
