Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573352, here are decompositions:

73 + 31573279 = 31573352
163 + 31573189 = 31573352
199 + 31573153 = 31573352
229 + 31573123 = 31573352
241 + 31573111 = 31573352
331 + 31573021 = 31573352
373 + 31572979 = 31573352
409 + 31572943 = 31573352

Showing the first eight; more decompositions exist.
