Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452042, here are decompositions:

23 + 31452019 = 31452042
29 + 31452013 = 31452042
43 + 31451999 = 31452042
73 + 31451969 = 31452042
113 + 31451929 = 31452042
173 + 31451869 = 31452042
241 + 31451801 = 31452042
311 + 31451731 = 31452042

Showing the first eight; more decompositions exist.
