Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562132, here are decompositions:

13 + 31562119 = 31562132
79 + 31562053 = 31562132
109 + 31562023 = 31562132
139 + 31561993 = 31562132
163 + 31561969 = 31562132
193 + 31561939 = 31562132
229 + 31561903 = 31562132
331 + 31561801 = 31562132

Showing the first eight; more decompositions exist.
