Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565752, here are decompositions:

59 + 31565693 = 31565752
89 + 31565663 = 31565752
149 + 31565603 = 31565752
191 + 31565561 = 31565752
353 + 31565399 = 31565752
401 + 31565351 = 31565752
443 + 31565309 = 31565752
461 + 31565291 = 31565752

Showing the first eight; more decompositions exist.
