Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562004, here are decompositions:

11 + 31561993 = 31562004
31 + 31561973 = 31562004
37 + 31561967 = 31562004
101 + 31561903 = 31562004
157 + 31561847 = 31562004
181 + 31561823 = 31562004
193 + 31561811 = 31562004
197 + 31561807 = 31562004

Showing the first eight; more decompositions exist.
