Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473574, here are decompositions:

137 + 31473437 = 31473574
311 + 31473263 = 31473574
383 + 31473191 = 31473574
401 + 31473173 = 31473574
467 + 31473107 = 31473574
491 + 31473083 = 31473574
647 + 31472927 = 31473574
683 + 31472891 = 31473574

Showing the first eight; more decompositions exist.
