Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575626, here are decompositions:

73 + 31575553 = 31575626
127 + 31575499 = 31575626
139 + 31575487 = 31575626
157 + 31575469 = 31575626
193 + 31575433 = 31575626
409 + 31575217 = 31575626
463 + 31575163 = 31575626
487 + 31575139 = 31575626

Showing the first eight; more decompositions exist.
