Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573002, here are decompositions:

23 + 31572979 = 31573002
31 + 31572971 = 31573002
53 + 31572949 = 31573002
59 + 31572943 = 31573002
61 + 31572941 = 31573002
101 + 31572901 = 31573002
179 + 31572823 = 31573002
193 + 31572809 = 31573002

Showing the first eight; more decompositions exist.
