Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562190, here are decompositions:

53 + 31562137 = 31562190
71 + 31562119 = 31562190
73 + 31562117 = 31562190
83 + 31562107 = 31562190
97 + 31562093 = 31562190
137 + 31562053 = 31562190
157 + 31562033 = 31562190
167 + 31562023 = 31562190

Showing the first eight; more decompositions exist.
