Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611236, here are decompositions:

73 + 31611163 = 31611236
109 + 31611127 = 31611236
193 + 31611043 = 31611236
199 + 31611037 = 31611236
457 + 31610779 = 31611236
463 + 31610773 = 31611236
607 + 31610629 = 31611236
673 + 31610563 = 31611236

Showing the first eight; more decompositions exist.
