Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562040, here are decompositions:

7 + 31562033 = 31562040
17 + 31562023 = 31562040
23 + 31562017 = 31562040
31 + 31562009 = 31562040
47 + 31561993 = 31562040
67 + 31561973 = 31562040
71 + 31561969 = 31562040
73 + 31561967 = 31562040

Showing the first eight; more decompositions exist.
