Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493652, here are decompositions:

11 + 31493641 = 31493652
41 + 31493611 = 31493652
53 + 31493599 = 31493652
59 + 31493593 = 31493652
79 + 31493573 = 31493652
83 + 31493569 = 31493652
131 + 31493521 = 31493652
139 + 31493513 = 31493652

Showing the first eight; more decompositions exist.
