Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931630, here are decompositions:

53 + 931577 = 931630
59 + 931571 = 931630
101 + 931529 = 931630
113 + 931517 = 931630
131 + 931499 = 931630
311 + 931319 = 931630
317 + 931313 = 931630
389 + 931241 = 931630

Showing the first eight; more decompositions exist.
