Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452044, here are decompositions:

3 + 31452041 = 31452044
31 + 31452013 = 31452044
37 + 31452007 = 31452044
163 + 31451881 = 31452044
313 + 31451731 = 31452044
331 + 31451713 = 31452044
457 + 31451587 = 31452044
523 + 31451521 = 31452044

Showing the first eight; more decompositions exist.
