Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456702, here are decompositions:

23 + 31456679 = 31456702
113 + 31456589 = 31456702
383 + 31456319 = 31456702
443 + 31456259 = 31456702
461 + 31456241 = 31456702
503 + 31456199 = 31456702
509 + 31456193 = 31456702
743 + 31455959 = 31456702

Showing the first eight; more decompositions exist.
