Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542224, here are decompositions:

61 + 31542163 = 31542224
157 + 31542067 = 31542224
193 + 31542031 = 31542224
211 + 31542013 = 31542224
223 + 31542001 = 31542224
331 + 31541893 = 31542224
367 + 31541857 = 31542224
397 + 31541827 = 31542224

Showing the first eight; more decompositions exist.
