Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562162, here are decompositions:

43 + 31562119 = 31562162
109 + 31562053 = 31562162
139 + 31562023 = 31562162
193 + 31561969 = 31562162
223 + 31561939 = 31562162
409 + 31561753 = 31562162
433 + 31561729 = 31562162
439 + 31561723 = 31562162

Showing the first eight; more decompositions exist.
