Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465442, here are decompositions:

79 + 31465363 = 31465442
199 + 31465243 = 31465442
313 + 31465129 = 31465442
331 + 31465111 = 31465442
373 + 31465069 = 31465442
409 + 31465033 = 31465442
439 + 31465003 = 31465442
661 + 31464781 = 31465442

Showing the first eight; more decompositions exist.
