Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562052, here are decompositions:

19 + 31562033 = 31562052
29 + 31562023 = 31562052
43 + 31562009 = 31562052
59 + 31561993 = 31562052
79 + 31561973 = 31562052
83 + 31561969 = 31562052
113 + 31561939 = 31562052
149 + 31561903 = 31562052

Showing the first eight; more decompositions exist.
