Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460744, here are decompositions:

43 + 31460701 = 31460744
67 + 31460677 = 31460744
97 + 31460647 = 31460744
163 + 31460581 = 31460744
193 + 31460551 = 31460744
313 + 31460431 = 31460744
331 + 31460413 = 31460744
397 + 31460347 = 31460744

Showing the first eight; more decompositions exist.
