Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562174, here are decompositions:

37 + 31562137 = 31562174
67 + 31562107 = 31562174
151 + 31562023 = 31562174
157 + 31562017 = 31562174
181 + 31561993 = 31562174
271 + 31561903 = 31562174
367 + 31561807 = 31562174
373 + 31561801 = 31562174

Showing the first eight; more decompositions exist.
