Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606226, here are decompositions:

139 + 31606087 = 31606226
313 + 31605913 = 31606226
349 + 31605877 = 31606226
499 + 31605727 = 31606226
607 + 31605619 = 31606226
643 + 31605583 = 31606226
709 + 31605517 = 31606226
787 + 31605439 = 31606226

Showing the first eight; more decompositions exist.
