Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606844, here are decompositions:

103 + 31606741 = 31606844
163 + 31606681 = 31606844
193 + 31606651 = 31606844
307 + 31606537 = 31606844
421 + 31606423 = 31606844
433 + 31606411 = 31606844
457 + 31606387 = 31606844
463 + 31606381 = 31606844

Showing the first eight; more decompositions exist.
