Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481362, here are decompositions:

41 + 31481321 = 31481362
113 + 31481249 = 31481362
131 + 31481231 = 31481362
173 + 31481189 = 31481362
191 + 31481171 = 31481362
239 + 31481123 = 31481362
251 + 31481111 = 31481362
389 + 31480973 = 31481362

Showing the first eight; more decompositions exist.
