Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452914, here are decompositions:

13 + 31452901 = 31452914
151 + 31452763 = 31452914
193 + 31452721 = 31452914
307 + 31452607 = 31452914
331 + 31452583 = 31452914
397 + 31452517 = 31452914
421 + 31452493 = 31452914
433 + 31452481 = 31452914

Showing the first eight; more decompositions exist.
