Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562104, here are decompositions:

5 + 31562099 = 31562104
11 + 31562093 = 31562104
47 + 31562057 = 31562104
71 + 31562033 = 31562104
131 + 31561973 = 31562104
137 + 31561967 = 31562104
257 + 31561847 = 31562104
281 + 31561823 = 31562104

Showing the first eight; more decompositions exist.
