Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562082, here are decompositions:

29 + 31562053 = 31562082
59 + 31562023 = 31562082
73 + 31562009 = 31562082
89 + 31561993 = 31562082
109 + 31561973 = 31562082
113 + 31561969 = 31562082
163 + 31561919 = 31562082
179 + 31561903 = 31562082

Showing the first eight; more decompositions exist.
