Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562822, here are decompositions:

43 + 31562779 = 31562822
139 + 31562683 = 31562822
199 + 31562623 = 31562822
211 + 31562611 = 31562822
229 + 31562593 = 31562822
271 + 31562551 = 31562822
373 + 31562449 = 31562822
433 + 31562389 = 31562822

Showing the first eight; more decompositions exist.
