Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562248, here are decompositions:

5 + 31562243 = 31562248
17 + 31562231 = 31562248
131 + 31562117 = 31562248
149 + 31562099 = 31562248
191 + 31562057 = 31562248
239 + 31562009 = 31562248
281 + 31561967 = 31562248
401 + 31561847 = 31562248

Showing the first eight; more decompositions exist.
