Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483786, here are decompositions:

53 + 31483733 = 31483786
137 + 31483649 = 31483786
233 + 31483553 = 31483786
239 + 31483547 = 31483786
293 + 31483493 = 31483786
317 + 31483469 = 31483786
353 + 31483433 = 31483786
479 + 31483307 = 31483786

Showing the first eight; more decompositions exist.
