Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536952, here are decompositions:

89 + 31536863 = 31536952
131 + 31536821 = 31536952
179 + 31536773 = 31536952
233 + 31536719 = 31536952
401 + 31536551 = 31536952
431 + 31536521 = 31536952
569 + 31536383 = 31536952
593 + 31536359 = 31536952

Showing the first eight; more decompositions exist.
