Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462430, here are decompositions:

67 + 31462363 = 31462430
73 + 31462357 = 31462430
79 + 31462351 = 31462430
157 + 31462273 = 31462430
163 + 31462267 = 31462430
409 + 31462021 = 31462430
487 + 31461943 = 31462430
607 + 31461823 = 31462430

Showing the first eight; more decompositions exist.
