Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562404, here are decompositions:

47 + 31562357 = 31562404
113 + 31562291 = 31562404
131 + 31562273 = 31562404
173 + 31562231 = 31562404
191 + 31562213 = 31562404
311 + 31562093 = 31562404
347 + 31562057 = 31562404
431 + 31561973 = 31562404

Showing the first eight; more decompositions exist.
