Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558594, here are decompositions:

131 + 31558463 = 31558594
257 + 31558337 = 31558594
311 + 31558283 = 31558594
383 + 31558211 = 31558594
461 + 31558133 = 31558594
467 + 31558127 = 31558594
521 + 31558073 = 31558594
761 + 31557833 = 31558594

Showing the first eight; more decompositions exist.
