Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495584, here are decompositions:

61 + 31495523 = 31495584
67 + 31495517 = 31495584
73 + 31495511 = 31495584
83 + 31495501 = 31495584
103 + 31495481 = 31495584
137 + 31495447 = 31495584
167 + 31495417 = 31495584
181 + 31495403 = 31495584

Showing the first eight; more decompositions exist.
