Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558714, here are decompositions:

41 + 31558673 = 31558714
107 + 31558607 = 31558714
251 + 31558463 = 31558714
281 + 31558433 = 31558714
431 + 31558283 = 31558714
461 + 31558253 = 31558714
491 + 31558223 = 31558714
503 + 31558211 = 31558714

Showing the first eight; more decompositions exist.
