Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488608, here are decompositions:

61 + 31488547 = 31488608
127 + 31488481 = 31488608
139 + 31488469 = 31488608
337 + 31488271 = 31488608
397 + 31488211 = 31488608
499 + 31488109 = 31488608
577 + 31488031 = 31488608
631 + 31487977 = 31488608

Showing the first eight; more decompositions exist.
