Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622590, here are decompositions:

11 + 31622579 = 31622590
53 + 31622537 = 31622590
71 + 31622519 = 31622590
317 + 31622273 = 31622590
353 + 31622237 = 31622590
383 + 31622207 = 31622590
401 + 31622189 = 31622590
443 + 31622147 = 31622590

Showing the first eight; more decompositions exist.
