Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452236, here are decompositions:

3 + 31452233 = 31452236
37 + 31452199 = 31452236
139 + 31452097 = 31452236
157 + 31452079 = 31452236
223 + 31452013 = 31452236
229 + 31452007 = 31452236
307 + 31451929 = 31452236
367 + 31451869 = 31452236

Showing the first eight; more decompositions exist.
