Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580294, here are decompositions:

37 + 31580257 = 31580294
61 + 31580233 = 31580294
73 + 31580221 = 31580294
181 + 31580113 = 31580294
211 + 31580083 = 31580294
241 + 31580053 = 31580294
457 + 31579837 = 31580294
463 + 31579831 = 31580294

Showing the first eight; more decompositions exist.
