Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461746, here are decompositions:

3 + 31461743 = 31461746
73 + 31461673 = 31461746
193 + 31461553 = 31461746
223 + 31461523 = 31461746
229 + 31461517 = 31461746
397 + 31461349 = 31461746
523 + 31461223 = 31461746
619 + 31461127 = 31461746

Showing the first eight; more decompositions exist.
