Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496210, here are decompositions:

37 + 31496173 = 31496210
127 + 31496083 = 31496210
199 + 31496011 = 31496210
313 + 31495897 = 31496210
331 + 31495879 = 31496210
409 + 31495801 = 31496210
457 + 31495753 = 31496210
547 + 31495663 = 31496210

Showing the first eight; more decompositions exist.
