Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573370, here are decompositions:

7 + 31573363 = 31573370
13 + 31573357 = 31573370
109 + 31573261 = 31573370
181 + 31573189 = 31573370
277 + 31573093 = 31573370
313 + 31573057 = 31573370
349 + 31573021 = 31573370
421 + 31572949 = 31573370

Showing the first eight; more decompositions exist.
