Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473754, here are decompositions:

47 + 31473707 = 31473754
173 + 31473581 = 31473754
317 + 31473437 = 31473754
491 + 31473263 = 31473754
503 + 31473251 = 31473754
563 + 31473191 = 31473754
593 + 31473161 = 31473754
647 + 31473107 = 31473754

Showing the first eight; more decompositions exist.
