Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452062, here are decompositions:

43 + 31452019 = 31452062
181 + 31451881 = 31452062
193 + 31451869 = 31452062
223 + 31451839 = 31452062
331 + 31451731 = 31452062
349 + 31451713 = 31452062
541 + 31451521 = 31452062
571 + 31451491 = 31452062

Showing the first eight; more decompositions exist.
