Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523302, here are decompositions:

23 + 31523279 = 31523302
59 + 31523243 = 31523302
71 + 31523231 = 31523302
101 + 31523201 = 31523302
191 + 31523111 = 31523302
281 + 31523021 = 31523302
401 + 31522901 = 31523302
479 + 31522823 = 31523302

Showing the first eight; more decompositions exist.
