Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486162, here are decompositions:

41 + 31486121 = 31486162
53 + 31486109 = 31486162
269 + 31485893 = 31486162
359 + 31485803 = 31486162
419 + 31485743 = 31486162
509 + 31485653 = 31486162
563 + 31485599 = 31486162
761 + 31485401 = 31486162

Showing the first eight; more decompositions exist.
