Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623272, here are decompositions:

61 + 31623211 = 31623272
73 + 31623199 = 31623272
103 + 31623169 = 31623272
151 + 31623121 = 31623272
211 + 31623061 = 31623272
313 + 31622959 = 31623272
349 + 31622923 = 31623272
379 + 31622893 = 31623272

Showing the first eight; more decompositions exist.
