Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623002, here are decompositions:

43 + 31622959 = 31623002
79 + 31622923 = 31623002
109 + 31622893 = 31623002
139 + 31622863 = 31623002
193 + 31622809 = 31623002
199 + 31622803 = 31623002
223 + 31622779 = 31623002
331 + 31622671 = 31623002

Showing the first eight; more decompositions exist.
