Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525572, here are decompositions:

5 + 31525567 = 31525572
19 + 31525553 = 31525572
73 + 31525499 = 31525572
83 + 31525489 = 31525572
151 + 31525421 = 31525572
193 + 31525379 = 31525572
229 + 31525343 = 31525572
241 + 31525331 = 31525572

Showing the first eight; more decompositions exist.
