Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534142, here are decompositions:

109 + 31534033 = 31534142
163 + 31533979 = 31534142
193 + 31533949 = 31534142
223 + 31533919 = 31534142
271 + 31533871 = 31534142
313 + 31533829 = 31534142
373 + 31533769 = 31534142
379 + 31533763 = 31534142

Showing the first eight; more decompositions exist.
