Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31561334, here are decompositions:

61 + 31561273 = 31561334
97 + 31561237 = 31561334
157 + 31561177 = 31561334
163 + 31561171 = 31561334
193 + 31561141 = 31561334
241 + 31561093 = 31561334
331 + 31561003 = 31561334
433 + 31560901 = 31561334

Showing the first eight; more decompositions exist.
