Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562422, here are decompositions:

131 + 31562291 = 31562422
149 + 31562273 = 31562422
179 + 31562243 = 31562422
191 + 31562231 = 31562422
389 + 31562033 = 31562422
449 + 31561973 = 31562422
503 + 31561919 = 31562422
599 + 31561823 = 31562422

Showing the first eight; more decompositions exist.
