Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542608, here are decompositions:

61 + 31542547 = 31542608
151 + 31542457 = 31542608
211 + 31542397 = 31542608
379 + 31542229 = 31542608
541 + 31542067 = 31542608
571 + 31542037 = 31542608
577 + 31542031 = 31542608
607 + 31542001 = 31542608

Showing the first eight; more decompositions exist.
