Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573676, here are decompositions:

37 + 31573639 = 31573676
163 + 31573513 = 31573676
283 + 31573393 = 31573676
313 + 31573363 = 31573676
397 + 31573279 = 31573676
487 + 31573189 = 31573676
523 + 31573153 = 31573676
619 + 31573057 = 31573676

Showing the first eight; more decompositions exist.
