Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452002, here are decompositions:

3 + 31451999 = 31452002
73 + 31451929 = 31452002
163 + 31451839 = 31452002
271 + 31451731 = 31452002
499 + 31451503 = 31452002
541 + 31451461 = 31452002
619 + 31451383 = 31452002
709 + 31451293 = 31452002

Showing the first eight; more decompositions exist.
