Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580594, here are decompositions:

37 + 31580557 = 31580594
271 + 31580323 = 31580594
277 + 31580317 = 31580594
337 + 31580257 = 31580594
373 + 31580221 = 31580594
541 + 31580053 = 31580594
547 + 31580047 = 31580594
757 + 31579837 = 31580594

Showing the first eight; more decompositions exist.
