Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573598, here are decompositions:

37 + 31573561 = 31573598
97 + 31573501 = 31573598
241 + 31573357 = 31573598
337 + 31573261 = 31573598
409 + 31573189 = 31573598
487 + 31573111 = 31573598
541 + 31573057 = 31573598
571 + 31573027 = 31573598

Showing the first eight; more decompositions exist.
