Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620590, here are decompositions:

13 + 31620577 = 31620590
19 + 31620571 = 31620590
73 + 31620517 = 31620590
103 + 31620487 = 31620590
109 + 31620481 = 31620590
181 + 31620409 = 31620590
193 + 31620397 = 31620590
367 + 31620223 = 31620590

Showing the first eight; more decompositions exist.
