Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452434, here are decompositions:

67 + 31452367 = 31452434
151 + 31452283 = 31452434
193 + 31452241 = 31452434
313 + 31452121 = 31452434
337 + 31452097 = 31452434
373 + 31452061 = 31452434
421 + 31452013 = 31452434
577 + 31451857 = 31452434

Showing the first eight; more decompositions exist.
