Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452152, here are decompositions:

31 + 31452121 = 31452152
73 + 31452079 = 31452152
139 + 31452013 = 31452152
223 + 31451929 = 31452152
271 + 31451881 = 31452152
283 + 31451869 = 31452152
313 + 31451839 = 31452152
421 + 31451731 = 31452152

Showing the first eight; more decompositions exist.
