Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473700, here are decompositions:

101 + 31473599 = 31473700
107 + 31473593 = 31473700
263 + 31473437 = 31473700
449 + 31473251 = 31473700
491 + 31473209 = 31473700
509 + 31473191 = 31473700
593 + 31473107 = 31473700
617 + 31473083 = 31473700

Showing the first eight; more decompositions exist.
