Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457846, here are decompositions:

3 + 31457843 = 31457846
103 + 31457743 = 31457846
109 + 31457737 = 31457846
127 + 31457719 = 31457846
139 + 31457707 = 31457846
367 + 31457479 = 31457846
397 + 31457449 = 31457846
463 + 31457383 = 31457846

Showing the first eight; more decompositions exist.
