Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589374, here are decompositions:

41 + 31589333 = 31589374
53 + 31589321 = 31589374
71 + 31589303 = 31589374
83 + 31589291 = 31589374
191 + 31589183 = 31589374
317 + 31589057 = 31589374
347 + 31589027 = 31589374
431 + 31588943 = 31589374

Showing the first eight; more decompositions exist.
