Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528142, here are decompositions:

31 + 31528111 = 31528142
73 + 31528069 = 31528142
211 + 31527931 = 31528142
229 + 31527913 = 31528142
313 + 31527829 = 31528142
433 + 31527709 = 31528142
439 + 31527703 = 31528142
601 + 31527541 = 31528142

Showing the first eight; more decompositions exist.
