Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532318, here are decompositions:

109 + 31532209 = 31532318
151 + 31532167 = 31532318
229 + 31532089 = 31532318
397 + 31531921 = 31532318
409 + 31531909 = 31532318
691 + 31531627 = 31532318
739 + 31531579 = 31532318
919 + 31531399 = 31532318

Showing the first eight; more decompositions exist.
