Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573610, here are decompositions:

97 + 31573513 = 31573610
109 + 31573501 = 31573610
331 + 31573279 = 31573610
349 + 31573261 = 31573610
421 + 31573189 = 31573610
457 + 31573153 = 31573610
487 + 31573123 = 31573610
499 + 31573111 = 31573610

Showing the first eight; more decompositions exist.
