Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623284, here are decompositions:

61 + 31623223 = 31623284
73 + 31623211 = 31623284
103 + 31623181 = 31623284
163 + 31623121 = 31623284
223 + 31623061 = 31623284
337 + 31622947 = 31623284
421 + 31622863 = 31623284
541 + 31622743 = 31623284

Showing the first eight; more decompositions exist.
