Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573736, here are decompositions:

97 + 31573639 = 31573736
109 + 31573627 = 31573736
223 + 31573513 = 31573736
373 + 31573363 = 31573736
379 + 31573357 = 31573736
457 + 31573279 = 31573736
547 + 31573189 = 31573736
613 + 31573123 = 31573736

Showing the first eight; more decompositions exist.
